وَلَا تَتَّخِذُوٓا۟ أَيْمَـٰنَكُمْ دَخَلًۢا بَيْنَكُمْ فَتَزِلَّ قَدَمٌۢ بَعْدَ ثُبُوتِهَا وَتَذُوقُوا۟ ٱلسُّوٓءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ ٱللَّهِ ۖ وَلَكُمْ عَذَابٌ عَظِيمٌ
Wa laa tattakhizooo aimaanakum dakhalam bainakum ftazilla qadamum ba'da subootihaa wa tazooqus sooo'a bimmaa sadattum 'an sabeelil laahi wa lakum 'azaabun 'azeem
Do not turn your oaths into a means of deceit among yourselves, lest a foot slip after being firmly planted, and you taste the bitterness of having turned others from the way of God — and a great punishment awaits you.
