وَلَا تَتَّخِذُوْۗا اَيْمَانَكُمْ دَخَلًۢا بَيْنَكُمْ فَتَزِلَّ قَدَمٌۢ بَعْدَ ثُبُوْتِہَا وَتَذُوْقُوا السُّوْۗءَ بِمَا صَدَدْتُّمْ عَنْ سَبِيْلِ اؘ۰ۚ وَلَكُمْ عَذَابٌ عَظِيْمٌ۹۴
Wala tattakhithoo aymanakum dakhalan baynakum fatazilla qadamun baAAda thubootiha watathooqoo alssooa bima sadadtum AAan sabeeli Allahi walakum AAathabun AAatheemun
So do not make your oaths a means of deceiving one another, lest your foot should slip after having found its hold, and you taste of evil for having hindered (others) from the way of God, and suffer a grievous punishment.
