سُنَنُ ابْنِ مَاجَهْ
Sunan Ibn Majah 2092
The Chapters on Expiation
The swearing of the Messenger of Allah (ﷺ) by which he would take an oath
حَدَّثَنَا أَبُو إِسْحَاقَ الشَّافِعِيُّ، إِبْرَاهِيمُ بْنُ مُحَمَّدِ بْنِ الْعَبَّاسِ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ رَجَاءٍ الْمَكِّيُّ، عَنْ عَبَّادِ بْنِ إِسْحَاقَ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ كَانَتْ أَكْثَرُ أَيْمَانِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ لاَ وَمُصَرِّفِ الْقُلُوبِ .
It was narrated from Salim that his father said: "The swearing most frequently sworn by the Messenger of Allah (ﷺ) was: 'No, by the Controller of the hearts."'
