Ibn al-Muththanna reported on the authority of Ibn Abu' Adi who transmitted on the authority of Ibn' Aun who narrated from al-Qasim and Ibrahim having said: I cannot differentiate the hadith of one from the other (Qasim and Ibrahim) that the Mother of the Believers (Allah be pleased with her) said this: Messenger of Allah, people have come back with two acts of worship. The rest of the hadith is the same.
