Surah An-Nisa' (Women) Verse 1
O mankind, fear your Lord, who created you from one soul and created from it its mate and dispersed from both of them many men and women. And fear Allah , through whom you ask one another, and the wombs. Indeed Allah is ever, over you, an Observer.
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.
