94وَلَا تَتَّخِذُوٓا۟ أَيْمَـٰنَكُمْ دَخَلًۢا بَيْنَكُمْ فَتَزِلَّ قَدَمٌۢ بَعْدَ ثُبُوتِهَا وَتَذُوقُوا۟ ٱلسُّوٓءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ ٱللَّهِ ۖ وَلَكُمْ عَذَابٌ عَظِيمٌ
[94] And (O Muslims,) do not make your oaths the means of deceiving one another lest (someone's) foot should slip after being firmly fixed95 and you may suffer the consequences of debarring other people from the Way of Allah, and undergo a severe torment.
95That is, "Someone,who might have been convinced of Islam, seeing your dishonest conduct should become disgusted and hold back from joining the Believers." For he might argue like this:"As these Muslims are not much different from the disbelievers in their morals and dealings, there is no reason why I should join them."
