"When the Prophet ﷺ took an oath he would say: 'By the One in Whose Hand is the soul of Muhammad."'  

كَانَ النَّبِيُّ ﷺ إِذَا حَلَفَ قَالَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ  

"The swearing of the Messenger of Allah ﷺ when he took an oath and I bear witness before Allah was: 'By the One in Whose Hand is my soul."'  

كَانَتْ يَمِينُ رَسُولِ اللَّهِ ﷺ التَّى يَحْلِفُ بِهَا أَشْهَدُ عِنْدَ اللَّهِ وَالَّذِي نَفْسِي بِيَدِهِ  

"The swearing most frequently sworn by the Messenger of Allah ﷺ was: 'No, by the Controller of the hearts."'  

كَانَتْ أَكْثَرُ أَيْمَانِ رَسُولِ اللَّهِ ﷺ لاَ وَمُصَرِّفِ الْقُلُوبِ  

"The swearing of the Messenger of Allah ﷺ was: 'No, and I ask Allah for forgiveness."'  

كَانَتْ يَمِينُ رَسُولِ اللَّهِ ﷺ لاَ وَأَسْتَغْفِرُ اللَّهَ
