أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ طَلْحَةَ بْنِ عَبْدِ الْمَلِكِ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ نَذَرَ أَنْ يُطِيعَ اللَّهَ فَلْيُطِعْهُ وَمَنْ نَذَرَ أَنْ يَعْصِيَ اللَّهَ فَلاَ يَعْصِهِ " .
It was narrated from 'Aishah that the Messenger of Allah said: "Whoever vows to obey Allah, let him obey Him, and whoever vows to disobey Allah, let him not disobey Him."
