وَءَاتُواْ ٱلنِّسَآءَ صَدُقَٰتِهِنَّ نِحۡلَةٗۚ فَإِن طِبۡنَ لَكُمۡ عَن شَيۡءٖ مِّنۡهُ نَفۡسٗا فَكُلُوهُ هَنِيٓـٔٗا مَّرِيٓـٔٗا

Wa aatun nisaaa'a sadu qaatihinna nihlah; fa in tibna lakum 'an shai'im minhu nafsan fakuloohu hanee'am mareee'aa

And give the women (on marriage) their dower as a free gift; but if they, of their own good pleasure, remit any part of it to you, Take it and enjoy it with right good cheer.

— An-Nisa' (ٱلنِّسَاء), 4:4
