Chapter 52: Characteristics of The Hypocrites And Rulings Concerning Them
Ibn 'Umar reported that when 'Abdullah b. Ubayy b. Salul died. His son 'Abdullah b. 'Abdullah (b. Ubayy) came to Allah' s Messenger (ﷺ) and begged him that he should give him his shirt which he would use as a coffin for his father, he gave him that. He then begged that he should conduct funeral prayer for him. Allah' s Messenger (ﷺ) had hardly got up to observe the prayer for him that 'Umar stood up and caught hold of the garment of Allah' s Messenger (ﷺ) and said: Allah' s Messenger, are you going to conduct prayer for this man, whereas Allah has forbidden you to offer prayer for him? Thereupon Allah' s Messenger (ﷺ) said: Allah has given me an option as He has said: " You may beg pardon for them or you may not beg pardon for them, and even if you beg pardon for them, seventy times" (ix. 80), and I am going to make an addition to the seventy. He was a hypocrite and Allah' s Messenger (ﷺ) offered prayer for him and Allah, the Exalted and Glorious, revealed this verse: " Do not offer prayer for any one of them at all and do not stand upon their graves for (offering prayer over them)" (ix. 84).
