An-Nahl 16:94

وَلَا تَتَّخِذُوٓاْ أَيۡمَٰنَكُمۡ دَخَلَۢا بَيۡنَكُمۡ فَتَزِلَّ قَدَمُۢ بَعۡدَ ثُبُوتِهَا وَتَذُوقُواْ ٱلسُّوٓءَ بِمَا صَدَدتُّمۡ عَن سَبِيلِ ٱللَّهِ وَلَكُمۡ عَذَابٌ عَظِيمٞ 94

And do not take your oaths as [means of] deceit between you, lest a foot slip after it was [once] firm, and you would taste evil [in this world] for what [people] you diverted from the way of Allah, and you would have [in the Hereafter] a great punishment
