Salim ibn Abd Allah

Sālim ibn ʿAbd Allāh ibn ʿUmar ibn al-Khaṭṭāb was a well known narrator of hadith (sayings of Muhammad), many of which he related first hand from either his father, Abd Allah ibn Umar (died 693), or his grandfather, the caliph Umar (r. 634-644). His paternal aunt was Hafsa bint Umar, one of Muhammad's wives.

Salim is mentioned in Malik ibn Anas's Muwatta regarding the Islamic practice of rada'a, where a woman becomes unmarriageable kin (mahram) by means of suckling:

"Yahya related to me from Malik from Nafi that Salim ibn Abd Allah ibn Umar informed him that A'isha umm al-mu'minin sent him away while he was being nursed to her sister Umm Kulthum bint Abi Bakr and said, "Suckle him ten times so that he can come in to see me." Salim said, "Umm Kulthum nursed me three times and then fell ill, so that she only nursed me three times. I could not go in to see A'isha because Umm Kulthum did not finish for me the ten times."

He, in Sahih al-Bukhari alone, relates three Hadiths.
