An Nahl Ayah 94

وَلَا تَتَّخِذُوٓاْ أَيْمَـٰنَكُمْ دَخَلاَۢ بَيْنَكُمْ فَتَزِلَّ قَدَمُۢ بَعْدَ ثُبُوتِهَا وَتَذُوقُواْ ٱلسُّوٓءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ ٱللَّهِ‌ۖ وَلَكُمْ عَذَابٌ عَظِيمٌ ٩٤ And do not take your oaths as a means of deceiving one another or your feet will slip after they have been firm. Then you will taste the evil ?consequences? of hindering ?others? from the Way of Allah, and you will suffer a tremendous punishment.
