It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "On the Day of Resurrection, good deeds like mountains will come following a man, and he will ask: Where have these come from? It will be said: Because of your son seeking forgiveness for you."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abdullah bin Atiyyah except Ibrahim bin Uyaynah."
