Abdullah bin Abbas reported,

The Prophet ﷺ said, "Vows are of two kinds. Whatever is made for the sake of Allah, its expiation is its fulfillment. Whatever is made for the sake of Satan, it is not to be fulfilled, and the one who made it must offer the expiation of an oath."

عن ابن عباس

عن النبي ﷺ قال: النذر نذران، فما كان لله فكفارته الوفاء، وما كان للشيطان فلا وفاء فيه، وعليه كفارة يمين.
