The Islamic State has a flag (Alam); whether it is a Liwaa' or Rayah, as deduced from the flags (Alwiyah) and banners (Rayat) of the first Islamic State, which the Messenger of Allah (saw) in al-Medina al-Munawwarah. The flag (Liwaa) is white, on which it is written "La Ilaha illa Allah, Muhammad Rasul Allah" with black script. It is tied to the leader (Amir) of the army and is used as a sign ('alam) to him. The evidence for this is what was narrated by Ibn Majah «أن النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ دخل مكة يوم الفتح ولواؤه أبيض» "That the Prophet (saw) entered Makkah on the day of its conquest while raising a white flag". Al-Nasaa'i also narrated that

«أنه صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ حين أمَّر أسامة بن زيد على الجيش ليغزو الروم عقد لواءه بيده»

"When the Prophet (saw) appointed Usama ibn Zayd as amir to the army for invading the Romans, he tied his flag with his own hands". The banner (Rayah) is black, on which it is written "La Ilaha illa Allah, Muhammad Rasul Allah" with white script. It is carried by the leaders of the army divisions, battalions, detachments, and other army units. The evidence for this is that the Prophet (saw), while being the leader of the army in Khaybar, he said: «لأعطين الراية غداً رجلاً يحب الله ورسوله، ويحبه الله ورسوله، فأعطاها علياً»

"I will give the Raya tomorrow to a man who loves Allah and His Messenger, and Allah and His Messenger love him; and he gave it to Ali". (Hadith is agreed upon) Thus, Ali, may Allah bless him, was considered then a leader of a division or a battalion in the Army. As for the evidence for the color, it is narrated by al-Tirmidhi, that Albaraa ibn 'Aazib said when he was asked about the banner of the Messenger of Allah (saw):

«كَانَتْ سَوْدَاءَ مُرَبَّعَةً مِنْ نَمِرَةٍ»

"It was black squared from Namira". It is spread amongst the soldiers and the people when the soldiers return back victorious. The evidence for that is narrated by Bukhari in the Great History "At-Tareekh Al-Kabeer" who said Abu Bakr told me, said Thana Salam Bin Sulaiman Abu Mundhir told me Asim Abu Wael from Al-Harith ibn Hassan ibn Kaladah Al-Bakri said:

«دَخَلْتُ الْمَسْجِدَ فَرَأَيْتُ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَائِمًا عَلَى الْمِنْبَرِ يَخْطُبُ وَفُلانٌ قَائِمٌ مُتَقَلِّدٌ السَّيْفَ فَإِذَا رَايَاتٌ سُودٌ تَخْفِقُ! قُلْتُ: مَا هَذَا؟ قالوا: عَمْرُو بْنُ الْعَاصِ قَدِمَ مِنْ جَيْشِ ذَاتِ السَّلاسِلِ»

"We came to Medina and we saw the Prophet (saw) on the Mimbar, with someone standing in front of him wearing his sword. There were black banners (rayaat) in front of the Messenger (saw). I asked ‘what are these banners?' They said, ‘It is Amr ibn al-Aas who has just arrived from an expedition". They had returned victorious and the banners were many to celebrate the victory...

Moreover, the adoption of the Prophet (saw) of a black banner which he tied it to the brigades and a white flag which he tied it to the armies' leaders is an act of the Prophet (saw) that we must follow his example. It is not exceptional to the Messenger (saw), because just as the Prophet (saw) entered Makkah with the flag (Liwaa), he also tied a flag to Osama, and also recognized the banner (Rayah) of Jafar and his brothers in Mu'ta. The Messenger Allah (saw) said mourning to the people the death of Zayd, Ja'far and Ibn Ruwahah before the soldiers brought the news

«أَخَذَ الرَّايَةَ زَيْدٌ فَأُصِيبَ، ثُمَّ أَخَذَهَا جَعْفَرٌ فَأُصِيبَ، ثُمَّ أَخَذَهَا عَبْدُ اللَّهِ بْنُ رَوَاحَةَ فَأُصِيبَ»

"Zayd took the banner (raya) but he was hit; and then Ja'far took it and he was hit; and then Ibn Ruwahah took it and he was hit" (Reported by Bukhari from Anas ibn Malik (ra)). The banner is of great significance in Islam, it was taken as a motto of Muslims to gather under it, and by it their ranks are distinguished. It is chosen for it the brave forefront in their people and in the army to keep it lifted apparent for the people to see it, and if it falls they lift it and show extreme courage to prevent it falling, as the Sahaba, may Allah be pleased with them, did in Mu'ta...

This is in regards to the flag and banner in the era of the Messenger of Allah (saw) and by his approval. Muslims should follow the example of the Messenger of Allah (saw) and make this flag their flag, and this banner their banner in the Islamic State, the Khilafah "Caliphate" Rashidah that they will establish soon, Allah willing, and if they do not follow the example of the Messenger of Allah (saw) there will be sedition (Fitnah)... And this is what is perceived and evident in the torn Ummah's body; as a result of multiple flags for the ripped states and factions!

This is the approved official flag of the state in Islam, as well as its banner... This is what is tied to the army leaders, lifted by the leaders in the wars and spread out amongst the soldiers... It is raised in the state institutions and departments... and is spread out amongst people in their festivals and in victory processions... This is the banner and the flag of the Islamic State following the example of the Messenger of Allah (saw).

As to the fact that some tribes used to take a flag with a special color in their wars to distinguish themselves, this is permissible. For example in war, the army of al-Sham can take a flag with a different color in addition to the black flag, and the army of Egypt can take also a flag with a different color in addition to the black flag... And this is from the permissible (Mubah). It was narrated in at-Tabarani in al-Kabeer on authority of Mazeeda al-Abdi' saying «إِنَّ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ عَقَدَ رَايَاتِ الْأَنْصَارِ فَجَعَلَهُنَّ صُفَرًا»

"The Prophet (saw) has knotted the flags of al-Ansar and made them yellow." And it was narrated from Ibn Abi Asem in al-Aahad and al-Mathani on the authority of Kurz bin Sama who said: «...وَإِنَّ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ عَقَدَ رَايَةَ بَنِي سُلَيْمٍ حَمْرَاءَ»

"....And the Prophet (saw) knotted the flag of Bani Suleim red". So this is from the permissible (mubah). Army brigades nowadays use badges to differentiate themselves other than the official flag of the state, and it is permissible also to differentiate the armies by their names, as if numbering each army of its armies, so it is called: the first army, the third army for example, or naming it by its wilayah from the wilayat, or a province from its provinces, so it is called: Al-Sham Army or the Aleppo Army for example, and it is permissible for these divisions to have a special flag that distinguishes them administratively, raised in addition to the state's flag.

Thus, the banner of the Islamic state has specific descriptions, which is the legitimate (Shari') banner, which under which Dar al-Islam is sheltered, and by which the armies of Islam are shielded, so you escape from the death of ignorance that the Messenger of Allah (saw) described in his Hadith which was narrated by Muslim

... وَمَنْ قَاتلَ تَحْتَ رَايَةٍ عِمِّيَّةٍ، يَغْضَبُ لِعَصَبَةٍ، أو يَدْعُو إِلى عَصبَةٍ، أو يَنْصُرُ عَصَبَة، فَقُتِلَ فَقِتْلَةٌ جَاهِليَّةٌ»

"...and whoever is killed while under a banner of ignorance, getting angry for the sake of tribalism or fighting for the sake of tribalism or calling to tribalism then his death is that of jahiliyya". In this case, he (saw) called it the banner of ignorance (Amiyah), "from the word "Ta'miyah" meaning blinding, which is disguising and is interpreted as misguiding (Dhalal)". The rest of the Hadith interpreted it as the one fighting for the sake of tribalism, without knowledge or guidance or an enlightening Book, for people or for a class or a tyrant or any issue other than for Allah, like the fighting of ignorance. Or fighting not in order to support the Deen and establish the rule of Allah or for Jihad to uphold the word of Allah, but fighting under the banner of ignorance as the Hadith mentioned, and then if he is killed, then his death is that of Jahiliyya. This Hadith had related the banner to the meaning and not to the form only. What supports this meaning is what came of the meaning of the flag as the purpose for the fighting. It was narrated from the Prophet (saw) about the Romans, where he said:

«... هُدْنَةٌ تَكُونُ بَيْنَكُمْ وَبَيْنَ بَنِي الأَصْفَرِ، فَيَغْدِرُونَ فَيَأْتُونَكُمْ تَحْتَ ثَمَانِينَ غَايَةً»

"....a treaty will be between you and the Romans, then they will betray you and march against you with eighty aims....", i.e. eighty banners. Hence the flag carries the idea and the purpose of which the fighting is for.

It is well known that states usually adopt flags to symbolize them and include slogans, drawings or words expressing their ideas and beliefs. They give them a kind of sanctity, and request from their citizens to have the symbol of loyalty to their homeland as their loyalty symbol. This is one of the international norms. From this aspect, the wrath of the West and their agents, the rulers of the damage, were provoked when the Muslims in Syria Ash-Sham adopted the flag; "Rayah or Liwaa", of the Prophet (saw). Some scholars embarked on issuing Fatwa to some factions on the doctrine of the rulers that it is permissible to take any form of banner or flag, and not necessary to commit to the banner of the Prophet (saw) and that it can be multiple. Thus, they were justifying for them to take the flags of Sykes-Picot, "Al-Amiaya" (ignorance), that was developed by the French and the British to entrench the concept of nationalism. So they made for each country of the Islamic countries a flag to be symbolized by. Thus these flags became a symbol of fragmentation and division, and a substitute for Al-Okab; the banner of the Messenger of Allah (saw). As these Kaffir colonists, the enemies of Islam have asked their agents, the Muslim rulers, to maintain the banners of division; because they know that the loyalty of these flags mean loyalty to the Kaffir colonists. And since the flag is a symbol of what it is put for; they are particularly keen to ensure that they are not touched except by their will. Thus, the fundamental problem with the West is that it rejects the Islamic flag; because it means that it was the flag of the State of the Prophet (saw), and because of it is afraid that it will be the flag of the promised Khilafah "Caliphate" Rashidah State which brings together Muslims under its rule. The root of the problem with these scholars is that their thought was not built on dissociation (Bara) from these rulers, and missed their minds that the Khilafah "Caliphate" State is a state that gathers Muslims under its presidency, and where loyalty is to Allah alone...

O Muslims: The Prophet (saw) has taken for the first Islamic State a banner and flag with clear and specific descriptions indicated by the text, and that Hizb ut Tahrir invites you to follow the example of the Prophet (saw) so that you would succeed...

((فَلْيَحْذَرِ الَّذِينَ يُخَالِفُونَ عَنْ أَمْرِهِ أَنْ تُصِيبَهُمْ فِتْنَةٌ أَوْ يُصِيبَهُمْ عَذَابٌ أَلِيمٌ))

"So let those beware who dissent from the Prophet's order, lest fitnah strike them or a painful punishment." [An-Nur: 63].
