وَلَا تَشۡتَرُواْ بِعَهۡدِ ٱللَّهِ ثَمَنٗا قَلِيلًاۚ إِنَّمَا عِندَ ٱللَّهِ هُوَ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ ٩٥
And do not exchange the covenant of Allāh for a small price. Indeed, what is with Allāh is best for you, if only you could know.
Translation: Saheeh International (English)
Each word's meaning and sound
Do not exchange the oath you took in Allah’s name for a small amount, not fulfilling the pledge or not being sincere in it. The victory and booty that Allah has in the world and the perpetual bliss that He has in the afterlife is better for you than the small amount that you take for breaking the pledge, if only you knew that.
