It was narrated from Abu Hurairah that the Prophet (ﷺ) said: “Whoever has the funeral prayer offered for him by one hundred Muslims, he will be forgiven.”

It was narrated that Kuraib the freed slave of ‘Abdullah bin ‘Abbas said: “A son of ‘Abdullah bin ‘Abbas died, and he said to me: ‘O Kuraib! Get up and see if anyone has assembled (to pray) for my son.’ I said: ‘Yes.’ He said: ‘Woe to you, how many do you see? Forty?’ I said: ‘No, rather there are more.’ He said: ‘Take my son out, for I bear witness that I hear the Messenger of Allah (ﷺ) say: “No (group of) forty believers intercede for a believer, but Allah will accept their intercession.”

Malik bin Hubairah Ash-Shami, who was a Companion of the Prophet (ﷺ), said: “If a funeral procession was brought and the number of people who followed it was considered to be small, they would be organized into three rows, then the funeral prayer would be offered.” He said: “The Messenger of Allah (ﷺ) said: ‘No three rows of Muslims offer the funeral prayer for one who has died, but he will be guaranteed (Paradise).’”
