It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty gave me the choice between His forgiving half of my Ummah and my choosing intercession, and I chose intercession, hoping that it would be more comprehensive for my Ummah. Were it not for the supplication in which that righteous servant preceded me, I would have hastened to make (my own special) supplication. When Allah Almighty removed from Sayyiduna Ishaq (peace be upon him) the distressing trial of being sacrificed, it was said to him: O Ishaq! Ask, and you will be given. He said: By Allah! I will seize this chance before the promptings of Satan come: 'Allahumma man mata la yushriku bika shay'an wa ahsana faghfir lahu wa adkhilhu al-jannah' (O Allah, whoever dies not associating anything with You and has done good, forgive him and admit him into Paradise)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Zayd bin Aslam (may Allah have mercy on him) except his son Abd al-Rahman (may Allah have mercy on him), and al-Walid bin Muslim (may Allah have mercy on him) is alone in narrating it."
