It is narrated about Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both). One of his sons passed away at Qudayd, or perhaps at ‘Usfan, so he said:“O Kurayb, check how many people have gathered for his funeral prayer.”The narrator says: I went outside and found that some people had gathered, so I informed Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) about it. He asked:“Are there forty people?”I replied:“Yes.”So Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said:“Bring out his body, for I heard the Noble Prophet (peace and blessings be upon him) say: ‘Whenever a Muslim passes away and forty people who do not associate anything with Allah perform his funeral prayer, Allah accepts their intercession for that deceased.’”
