Sahih Muslim 200
Sahih Muslim · Book 1: The Book of Faith · The Prophet (saws) will defer his supplication in order to intercede for his ummah
Muhammad b. 'Abd al-A'la reported it to me:
وَحَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى ، حَدَّثَنَا الْمُعْتَمِرُ ، عَنْ أَبِيهِ ، عَنْ أَنَسٍ ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم قَالَ فَذَكَرَ نَحْوَ حَدِيثِ قَتَادَةَ عَنْ أَنَسٍ .
Mu'tamir narrated to us on the authority of his father who transmitted it liom Anas that verity the Messenger of Allah (ﷺ) said, and then narrated the hadith like the one transmitted by Qatada on the authority of Anas.
