Surat An-Nahl (The Bee) - النحل

وَلَا تَتَّخِذُوٓا۟ أَيْمَٰنَكُمْ دَخَلًۢا بَيْنَكُمْ فَتَزِلَّ قَدَمٌۢ بَعْدَ ثُبُوتِهَا وَتَذُوقُوا۟ ٱلسُّوٓءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ ٱللَّهِ وَلَكُمْ عَذَابٌ عَظِيمٌ ﴿٩٤﴾

And do not make your oaths a means of deceit between you, lest a foot should slip after its stability and you should taste evil because you turned away from Allah's way and grievous punishment be your (lot).
