حَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا فُلَيْحٌ، حَدَّثَنِي نُعَيْمُ بْنُ عَبْدِ اللَّهِ، عَنْ سَالِمٍ، مَوْلَى شَدَّادِ بْنِ الْهَادِ قَالَ كُنْتُ أَنَا مَعَ، عَائِشَةَ - رضى الله عنها - فَذَكَرَ عَنْهَا عَنِ النَّبِيِّ صلى الله عليه وسلم بِمِثْلِهِ .
Salim, the freed slave of Shaddad b. al-Had said: I was in the presence of 'A'isha, and then narrated on her authority a hadith like this from the Prophet (way peace be upon him).
