Dan berikanlah kepada perempuan-perempuan itu maskahwin-maskahwin mereka sebagai pemberian yang wajib. Kemudian jika mereka dengan suka hatinya memberikan kepada kamu sebahagian dari maskahwinnya maka makanlah (gunakanlah) pemberian (yang halal) itu sebagai nikmat yang lazat, lagi baik kesudahannya.
