حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنِ الشَّيْبَانِيِّ، عَنْ عَبْدِ الرَّحْمَنِ، بْنِ الأَسْوَدِ عَنْ أَبِيهِ، قَالَ سَأَلْتُ عَائِشَةَ عَنِ الرُّقْيَةِ، فَقَالَتْ رَخَّصَ رَسُولُ اللَّهِ صلى الله عليه وسلم لأَهْلِ بَيْتٍ مِنَ الأَنْصَارِ فِي الرُّقْيَةِ مِنْ كُلِّ ذِي حُمَةٍ .
