Quran 16:94 — The Bee (Al-Nahl)

Do not abuse the oaths among you, lest you slide back after having a strong foothold, then you incur misery. Such is the consequence of repelling from the path of GOD (by setting a bad example); you incur a terrible retribution.

[16:93] Had GOD willed, He could have made you one congregation. But He sends astray whoever chooses to go astray, and He guides whoever wishes to be guided.* You will surely be asked about everything you have done.

[16:95] Do not sell your oaths before GOD short . What GOD possesses is far better for you, if you only knew.
