It is a must for every conscious Muslim to know the details of the Black Flag Band of Khorasan. Because the Messenger of Allah (pbuh) has given us a strict command that if the black flag-carrying group of Khorasan rises, you will join them even if you crawl on the ice. That is, it is obligatory for every Muslim to join the black flag-carrying party of Khorasan.

Kalema Black Flag

On the authority of Hazrat Choban (RA), the Messenger of God, may God bless him and grant him peace, said, “When you see the black flags coming from the direction of Khorasan, join them. Because Allah's Caliph Mahdi will be among them.

On the authority of Hazrat Abdullah Ibn Harith (R.A.), Rasulullah Sallallahu Alaihi Wasallam said, "Some people will emerge from the east (Khorasan) who will help establish the Caliphate of Imam Mahdi and facilitate the establishment of the Caliphate."

Hazrat Abdullah Ibn Masood (RA) said, "Once we were present at the service of the Prophet (PBUH). He was saying, "A group will come from that direction (he pointed to the east with his hand). They will be black flag bearers. They will demand the truth (full Islamic rule), but it will not be given to them. Twice or thrice he would make such a claim, but the then rulers would not accept it.

In the end they will hand over (the responsibility of Islamic governance) to a man from my family (Imam Mahdi). He will fill the earth with justice and righteousness, just as it was once filled with unjust oppression. So if any of you are alive at that time, surely join their party - even if you have to come on your elbows on ice”.

On the authority of Hazrat Abu Huraira (RA), the Messenger of God, may God bless him and grant him peace, said,
“When the black flags come out from the east (Khorasan), nothing will be able to resist them. Even this flag will be hoisted (establishing the Caliphate) in Ilya (Baitul Muqaddas)”.
