وَحَدَّثَنِي أَبُو الرَّبِيعِ الزَّهْرَانِيُّ ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ ، حَدَّثَنَا الأَعْمَشُ ، عَنْ إِبْرَاهِيمَ ، عَنِ الأَسْوَدِ ، عَنْ عَائِشَةَ ، وَعَنِ الأَعْمَشِ ، عَنْ مُسْلِمٍ ، عَنْ مَسْرُوقٍ ، عَنْ عَائِشَةَ ، بِمِثْلِهِ .
A hadith like this has been transmitted on the authority of 'A'isha through another chain of narrators.
