Forbidden are : your mothers, your daughters, your sisters, your paternal and maternal aunts, your nieces on the brother and sister's side, your foster - mothers, your foster- sisters, your mothers - in - law, your step -daughters with whose mothers you have consummated marriage, but you are absolved to marry them if you have annulled your unconsummated marriage to their mothers -your daughters-in- law whose husbands are your own sons who generated from your own loins. Nor can you effect a, matrimonial union with two sisters at the same time; bygone shall be bygone; the new era shall begin; indeed Allah has always been Ghafurun (Forgiving) and Rahimun.
