Oaths and Vows (Kitab Al-Aiman Wa Al-Nudhur)
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ النُّفَيْلِيُّ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ : أَكْثَرُ مَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَحْلِفُ بِهَذِهِ الْيَمِينِ : " لاَ، وَمُقَلِّبِ الْقُلُوبِ " .
Narrated Ibn 'Umar:The oath which the Messenger of Allah (ﷺ) often used was this: No, by Him who overturns the hearts
