Narrated Abdullah bin Umar (may Allah be pleased with them): When Abdullah bin Ubayy (the hypocrite) died, his son (Abdullah, the companion) came to the Prophet Muhammad (peace and blessings be upon him) and requested, "O Messenger of Allah! Please grant your shirt for my father's shroud, pray over him, and seek forgiveness for him." So the Prophet (peace and blessings be upon him), out of the utmost kindness, gave his shirt and said, "Inform me, and I will lead the funeral prayer." Abdullah sent word, and when the Prophet (peace and blessings be upon him) stepped forward to lead the prayer, Umar (may Allah be pleased with him) caught hold of him from behind and said, "Has Allah not forbidden you to pray the funeral prayer for the hypocrites?" The Prophet (peace and blessings be upon him) replied, "I have been given a choice, as Allah has said: 'Whether you ask forgiveness for them or do not ask forgiveness for them, and even if you ask forgiveness for them seventy times, Allah will never forgive them.'" So the Prophet (peace and blessings be upon him) led the prayer. After that, the following verse was revealed: "Never pray the funeral prayer for any of them (the hypocrites) who dies."
