An Nahl, 94 Ayah
16:94
وَلَا تَتَّخِذُوٓاْ أَيۡمَٰنَكُمۡ دَخَلَۢا بَيۡنَكُمۡ فَتَزِلَّ قَدَمُۢ بَعۡدَ ثُبُوتِهَا وَتَذُوقُواْ ٱلسُّوٓءَ بِمَا صَدَدتُّمۡ عَن سَبِيلِ ٱللَّهِ وَلَكُمۡ عَذَابٌ عَظِيمٞ ٩٤
Wa Lā Tattakhidhū 'Aymānakum Dakhalāan Baynakum Fatazilla Qadamun Ba`da Thubūtihā Wa Tadhūqū As-Sū'a Bimā Şadadtum `An Sabīli Al-Lahi ۖ Wa Lakum `Adhābun `Ažīmun
And do not take your oaths as [means of] deceit between you, lest a foot slip after it was [once] firm, and you would taste evil [in this world] for what [people] you diverted from the way of Allah, and you would have [in the Hereafter] a great punishment.
