MUHAMMAD’S TEACHINGS TO MANKIND
“ The Messenger of God, peace and blessings of God be upon him, said, "Indeed, God forbade by breastfeeding (1) what is forbidden by kinship (2) (with regards to marriage)." Footnotes: 1. A woman becomes a child's breastfeeding mother only if she nurses that child five times during its first two years of life and thus becomes forbidden to him in marriage. 2. Specified in the verse: “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. Indeed, Allah is ever Forgiving and Merciful.” an-Nisā' 4:23 ”
