Sura al-Naḥl 16:94

وَلَا تَتَّخِذُوٓا۟ أَيْمَٰنَكُمْ دَخَلًۢا بَيْنَكُمْ فَتَزِلَّ قَدَمٌۢ بَعْدَ ثُبُوتِهَا وَتَذُوقُوا۟ ٱلسُّوٓءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ ٱللَّـهِ وَلَكُمْ عَذَابٌ عَظِيمٌ

wa-lā tattakhidhū aymānakum dakhalan baynakum fatazilla qadamun baʿda thubūtihā wa-tadhūqū l-sūa bi-mā ṣadadttum ʿan sabīli allāhi wa-lakum ʿadhābun ʿaẓīmun

And take not your oaths, to practise deception between yourselves, with the result that someone's foot may slip after it was firmly planted, and ye may have to taste the evil (consequences) of having hindered (men) from the Path of Allah, and a Mighty Wrath descend on you.
