Quran An-Nisa 4:4

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

Translation

And give the women [upon marriage] their [bridal] gifts graciously. But if they give up willingly to you anything of it, then take it in satisfaction and ease.
