An-Nisá 4:23 حرمت عليكم امهاتكم وبناتكم واخواتكم وعماتكم وخالاتكم وبنات الاخ وبنات الاخت وامهاتكم اللاتي ارضعنكم واخواتكم من الرضاعة وامهات نسايكم وربايبكم اللاتي في حجوركم من نسايكم اللاتي دخلتم بهن فان لم تكونوا دخلتم بهن فلا جناح عليكم وحلايل ابنايكم الذين من اصلابكم وان تجمعوا بين الاختين الا ما قد سلف ان الله كان غفورا رحيما ٢٣

˹Also˺ forbidden to you for marriage are 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 stepdaughters under your guardianship if you have consummated marriage with their mothers—but if you have not, then you can marry them—nor the wives of your own sons, nor two sisters together at the same time—except what was done previously. Surely Allah is All-Forgiving, Most Merciful.

Prohibited to you [for marriage] are your mothers, your daughters, your sisters, your father's sisters, your mother's sisters, your brother's daughters, your sister's daughters, your [milk] mothers who nursed you, your sisters through nursing, your wives' mothers, and your step-daughters under your guardianship [born] of your wives unto whom you have gone in. But if you have not gone in unto them, there is no sin upon you. And [also prohibited are] the wives of your sons who are from your [own] loins, and that you take [in marriage] two sisters simultaneously, except for what has already occurred.¹ Indeed, Allāh is ever Forgiving and Merciful.
