Abu Bakkar Al-Hakam bin Farrukh said:

"Abu Al-Malih led us in offering the funeral prayer and we thought that he had said the Takbir, but he turned to us and said: 'Make you rows straight and intercede properly.' Abu Al-Malih said: Abdullah - meaning Ibn Salit-narrated to me that one of the Mothers of the believes, Maimunah the wife of the Prophet, said: The Prophet (ﷺ) told me: There is no deceased person for whom a group of people offers the funeral prayer, but their intercession for him will be accepted.' I asked Abu Al-Malih about the (number of that) group and he said: 'Forty."'
