Sunan Abi Dawud 3897
سنن أبي داود#3897SahihKharijah b. al-Salt quoted his parental uncle as saying that he passed (some people) :He recited Surat al-Fatihah over him for three days morning and evening. Whenever he finished it, he collected some of his saliva and spat it out, and he seemed as if he were set free from a bond. They gave him something as payment. He then came to the Prophet (ﷺ). He then transmitted the rest of the tradition to the same effect as Musaddad narrated
