[Machine] The Messenger of Allah ﷺ used to never break his oath until Allah revealed the expiation for oaths. He said, "I will not swear by an oath, seeing something better than it, unless I expiate for the oath and then do what is better."
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا حَلَفَ عَلَى يَمِينٍ لَا يَحْنَثُ حَتَّى أَنْزَلَ اللَّهُ تَعَالَى كَفَّارَةَ الْيَمِينِ فَقَالَ «لَا أَحْلِفُ عَلَى يَمِينٍ فَأَرَى غَيْرَهَا خَيْرًا مِنْهَا إِلَّا كَفَّرْتُ عَنْ يَمِينٍ ثُمَّ أَتَيْتُ الَّذِي هُوَ خَيْرٌ»
