Abu Bakr bin 'Ayyash al-Asadi أبو بكر بن عياش بن سالم الأسدي · Chapters Regarding Funerals

“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).’”

“I heard the Messenger of Allah (ﷺ) say: ‘The (funeral) prayer should be offered for a child.’”

“And that they will not disobey you in Ma’ruf (all that is good in Islam);” he said: “(It is about) wailing.”
