Volume 6, Book 60, Number 194:
Narrated Ibn Umar:
When Abdullah bin Ubai died, his son ‘Abdullah bin ‘Abdullah came to Allah’s Apostle who gave
his shirt to him and ordered him to shroud his father in it. Then he stood up to offer the funeral
prayer for the deceased, but ‘Umar bin Al-Khattab took hold of his garment and said, “Do you offer
the funeral prayer for him though he was a hypocrite and Allah has forbidden you to ask forgiveness
for hypocrites?” The Prophet said, “Allah has given me the choice (or Allah has informed me) saying:
“Whether you, O Muhammad, ask forgiveness for them, or do not ask forgiveness for them, even if
you ask forgiveness for them seventy times, Allah will not forgive them,” (9.80) The he added, “I will
(appeal to Allah for his sake) more than seventy times.” So Allah’s Apostle offered the funeral prayer
for him and we too, offered the prayer along with him. Then Allah revealed: “And never, O
Muhammad, pray (funeral prayer) for anyone of them that dies, nor stand at his grave. Certainly
they disbelieved in Allah and His Apostle and died in a state of rebellion.” (9.84)
