أَخْبَرَنَا حَجَّاجٌ ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ ، حَدَّثَنَا أَيُّوبُ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ : أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :" مَنْ حَلَفَ عَلَى يَمِينٍ، ثُمَّ قَالَ : إِنْ شَاءَ اللَّهُ، فَهُوَ بِالْخِيَارِ : إِنْ شَاءَ فَعَلَ، وَإِنْ شَاءَ لَمْ يَفْعَلْ "

Hajjaj told us, Hammad bin Salamah told us, Ayoub told us, on the authority of Nafi’, on the authority of Ibn Umar: that the Messenger of God, may God bless him and grant him peace, said “Whoever takes an oath and then says: God willing, he has the choice: if he wishes, he may do it, and if he wishes, he may not do it.”
