أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ حَدَّثَنَا ابْنُ إِدْرِيسَ، عَنْ عُبَيْدِ اللَّهِ، عَنْ طَلْحَةَ بْنِ عَبْدِ الْمَلِكِ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ نَذَرَ أَنْ يُطِيعَ اللَّهَ فَلْيُطِعْهُ وَمَنْ نَذَرَ أَنْ يَعْصِيَ اللَّهَ فَلاَ يَعْصِهِ " .
