(a) Ibn Abi Dhi'b narrates from Shu'bah, the freed slave of Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): I used to lead Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) to the place of Eid prayer; he would offer voluntary prayer in the mosque, and then would not come back to it again. (b) Azraq bin Qays narrates from them: I heard from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) about a man who used to pray on the day of Eid before the imam came out and before the prayer. He said: Allah Almighty does not turn back upon a servant the good deed that he does for Him.
