أَخْبَرَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ ، عَنْ أَيُّوبَ ، عَنِ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :" مَنْ حَلَفَ عَلَى يَمِينٍ، ثُمَّ قَالَ : إِنْ شَاءَ اللَّهُ، فَقَدِ اسْتَثْنَى "

Abu Al-Walid Al-Tayalisi told us, Hammad bin Salamah told us, on the authority of Ayyub, on the authority of Nafi’, on the authority of Ibn Umar, on the authority of the Prophet, may God’s prayers and peace be upon him. And he said: “Whoever takes an oath and then says: God willing, he will make an exception.”
