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

Do not use your oaths to deceive each other lest any foot should slip after being firmly placed and lest you should taste the penalty for having hindered others from the path of God, and suffer terrible torment.
And make not your oaths a means of deception among yourselves, lest a foot should slip after being firmly planted, and you may have to taste the evil (punishment in this world) of having hindered (men) from the Path of Allâh (i.e. Belief in the Oneness of Allâh and His Messenger, Muhammad صلى الله عليه و سلم), and yours will be a great torment (i.e. the Fire of Hell in the Hereafter).
