And those who cannot find a match must keep chaste until Allah grants them sufficiency out of His Bounty. And if any of the male and female slaves desires a deed of freedom, write it out for them if you ensure good for them by way of rehabilitation. (4:5-6). Give them from Allah's wealth that He has given you. Never hold your slave maidens for worldly gains from preserving their chastity by marrying if they so desire, lest they resort to lewdness. If anyone forces them, then after this compulsion Allah will be Forgiving, Merciful to them. (And He will hold the one who forces them, accountable).
