Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: I heard Sayyiduna Umar bin Khattab (may Allah be pleased with him) saying: When Abdullah bin Ubayy passed away, his son Abdullah came to the service of the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! This is Abdullah bin Ubayy, whom we have placed (on the bier), please perform his funeral prayer. So the Prophet (peace and blessings be upon him) stood up. When you (peace and blessings be upon him) stood to perform his funeral prayer, I came and stood in front of the Prophet (peace and blessings be upon him) and said: O Messenger of Allah (peace and blessings be upon him)! Will you perform the funeral prayer of the enemy of Allah who said such and such on such and such a day, and said such and such on such and such a day? I mentioned to you several of his wicked days. The Prophet (peace and blessings be upon him) smiled. He (peace and blessings be upon him) said: Leave me, O Umar! When I insisted more, he (peace and blessings be upon him) said: Leave me, O Umar, for I have been given a choice and I have chosen (what I prefer). Allah the Exalted has said: "Whether you ask forgiveness for them or do not ask forgiveness for them..." (The Prophet, peace and blessings be upon him, said) If I knew that if I sought forgiveness for him more than seventy times, he would be forgiven, I would do so more than that. Sayyiduna Umar (may Allah be pleased with him) says: Now I am amazed at my boldness before the Prophet (peace and blessings be upon him). In any case, Allah and His Messenger knew best. When the Prophet (peace and blessings be upon him) said this to me, I moved away from him. The Prophet (peace and blessings be upon him) performed his funeral prayer, accompanied his funeral, and stood by his grave until he was buried, then returned. By Allah! Shortly after that, Allah the Exalted revealed this verse: "And never pray [the funeral prayer] over any of them who dies, nor stand at his grave." After that, the Prophet (peace and blessings be upon him) never performed the funeral prayer of any hypocrite, nor did he stand by the grave of any hypocrite.
