Verses from Sura 16 – The Bee (Al-Nahl) النحل
Violating Your Oath: A Serious Offense
94. 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.
95. Do not sell your oaths before GOD short . What GOD possesses is far better for you, if you only knew.
96. What you possess runs out, but what GOD possesses lasts forever. We will surely reward those who steadfastly persevere; we will recompense them for their righteous works.
