The hadith is found in Sahih Muslim (1453a) and Sunan Abu Dawood (2061), where Salim, a freed slave of Abu Hudhayfa, was raised in his household like a son. When the hijab (modesty) ruling came, his presence in the house became a concern. Umm Salama and other wives of the Prophet (ﷺ) asked about this, and the Prophet (ﷺ) permitted Salim’s foster mother to breastfeed him, making him her mahram through foster kinship (ridha‘a). Tafsir & Scholarly Explanation Specific to Salim’s Case Most scholars, including Imam Malik, Abu Hanifa, and Ash-Shafi'i, ruled that this was a one-time ruling (Khusūsiyya) specific to Salim and not a general law. Later hadiths confirm that the Prophet's wives did not permit such breastfeeding after this case (Sahih Muslim 1454). Foster Relationship (Ridha’a) In Islam, if a child under two years old is breastfed five times or more, he/she becomes a mahram to the woman (Sahih Muslim 1452a). The Salim case was exceptional, as he was already an adult, and some scholars interpret this as symbolic rather than actual breastfeeding. Modern Interpretation Many scholars argue that actual breastfeeding did not take place; rather, milk was extracted and given to drink. Ibn al-Qayyim and others clarify that no direct contact happened, as modesty is a key principle in Islam. Final Ruling The majority of scholars reject adult breastfeeding as a means to establish mahram relationships today. The ruling in Salim’s case was an exception, not a general law.
