It is prohibited for you [to marry] your mothers, your daughters, your sisters, your paternal and maternal aunts, your brother’s daughters, your sister’s daughters, your foster mothers, your foster sisters, your mothers-in-law, your step-daughters under your guardianship if you have consummated the marriage with their mothers – however if you have not consummated the marriage, it is not a sin [to marry them] – nor wives of your own sons, nor two sisters together, except for what happened in the past, for Allah is All-Forgiving, Most Merciful.
