Bin Babawaih narrates from Abdallah bin Abbas that one day the Prophet (S) was sitting in the Qiba Mosque with his Companions. He said, “The first person who enters the door of the Mosque will be destined for the Heaven.”Hearing this, some companions got up to leave and grasp the privilege of entering the mosque first. The Prophet added, “many persons will enter this mosque and everyone will try to preempt the others, but the one amongst them who informs about the ending of the month of Azur? will be destined for the Heaven!”
Abu Dharr entered the Mosque along with the other persons. The Prophet (S) asked the gathering about the current month of the Roman Calendar. Abu Dharr replied that it was the end of the month of Azur?. The Prophet (S) said that he was aware of the fact but he wished to impress on the gathering that Abu Dharr was destined for the Heaven.
The Prophet (S) further added that this Heavenly person will be banished by the people because of his profound love for my family and that he would spend the rest of his life in a desolate place and die a lonely and hapless death! The people of Iraq would give him a burial taking pity on him. These persons too will be in the Heaven that has been promised by Allah to the benevolent.
Imam Ja’far As-Sadiq (as) also said that there are ten stages of faith. He added that Salman was on the tenth stage, Abu Dharr on the ninth, and Miqdad on the eighth stage!
