Hadith 4213
Lady Aisha Siddiqa (may Allah be pleased with her) narrates: The Prophet Muhammad (peace and blessings be upon him) instructed the wife of Abu Hudhaifah (may Allah be pleased with him), Lady Sahla (may Allah be pleased with her), to breastfeed Abu Hudhaifah’s slave, Salim, so that Abu Hudhaifah’s temperament (i.e., anger) would subside. So that woman breastfed that young man who was a grown man. The narrator named Rabee’ah says: This was a concession specifically for Salim.
