ভূমিকা
In the Tradition of the Cloak , the Holy Prophet (SA) also defines the position of Imam Ali (AS) by mentioning four different roles which he assumes in relation to the Prophet. They are as follows: 1) Brother 2) Successor (Wasi) 3) Vicegerent (Caliph) 4) Bearer of the standard or flag Each of these roles is great in its scope and is in itself enough to bring immense honor to the person who assumes that role. One can only imagine how great and virtuous such person who assumes all four roles is.
Role Of Brotherhood After migrating to Al-Madinah the Muhajiroon (the Migrants) and the Ansar (The Local Helpers) became so friendly with one another as if there was no difference of the tribe or the place of origin between them. It appeared that all of them belonged to one large family. They treated their properties as common, their honor and respect as common, and shared their happiness and sorrows together. This was a true example of unity and integrity.
To make these bonds stronger, the Prophet (SA) repeated the establishment of brotherhood between individuals of the two groups as he had done with those in Makkah. In the view of experts, brotherhood can be strong only between individuals of the same nature. If the natures are different, and the individuals come together for whatever reason, the togetherness will be temporary. The Prophet (AS) kept this factor in mind when he established brotherhood between individuals from the two groups.
He closely studied the natures of the individuals before declaring them brothers. When he saw that any two persons had a lot in common, he named them brothers. According to many narrations including Al Hakim in his Mustadrak , Ibn Abbas said: “The Holy Prophet (SA) assigned brotherhood among his companions, so he assigned Abi Bakr to Umar, Talha to Zubair, and ‘Uthman ibn A'ffan to Abdul Rahman ibn Uof.
So Ali ibn Abi Talib said to the Prophet, “Oh Messenger of Allah, you have designated brotherhood among your companions, so who is my brother?
