باب اخْتِبَاءِ النَّبِيِّ صلى الله عليه وسلم دَعْوَةَ الشَّفَاعَةِ لأُمَّتِهِ ‏‏
Sahih Muslim 200 d

Muhammad b. 'Abd al-A'la reported it to me:

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.
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 ‏.‏
