Sahih Muslim 1211 s
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.
وَحَدَّثَنَا ابْنُ الْمُثَنَّى، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنِ ابْنِ عَوْنٍ، عَنِ الْقَاسِمِ، وَإِبْرَاهِيمَ، - قَالَ لاَ أَعْرِفُ حَدِيثَ أَحَدِهِمَا مِنَ الآخَرِ - أَنَّ أُمَّ الْمُؤْمِنِينَ - رضى الله عنها - قَالَتْ يَا رَسُولَ اللَّهِ يَصْدُرُ النَّاسُ بِنُسُكَيْنِ ‏.‏ فَذَكَرَ الْحَدِيثَ ‏.‏
