"The Messenger of Allah said: 'Whoever swears an oath and says: If Allah wills, then he has made an exception.'"  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ حَلَفَ فَقَالَ إِنْ شَاءَ اللَّهُ فَقَدِ اسْتَثْنَى  

"The Messenger of Allah said: 'Whoever swears an oath and says: If Allah wills, then he has made an exception.'"  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ حَلَفَ فَقَالَ إِنْ شَاءَ اللَّهُ فَقَدِ اسْتَثْنَى  

"Whoever swears an oath and says, 'If Allah wills,' then he has the choice: If he wishes, he may go ahead, and if he wishes he may not."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ حَلَفَ عَلَى يَمِينٍ فَقَالَ إِنْ شَاءَ اللَّهُ فَهُوَ بِالْخِيَارِ إِنْ شَاءَ أَمْضَى وَإِنْ شَاءَ تَرَكَ
