Chapter: Ar-Rahm, i.e., womb (bond of kinship) remains fresh and fruitful if one looks after it always
Narrated `Amr bin Al-`As:
I heard the Prophet (ﷺ) saying openly not secretly, "The family of Abu so-and-so (i.e. Talib) are not among my protectors." `Amr said that there was a blank space (1) in the Book of Muhammad bin Ja`far. He added, "My Protector is Allah and the righteous believing people." `Amr bin Al-`As added: I heard the Prophet (ﷺ) saying, 'But they (that family) have kinship (Rahm) with me and I will be good and dutiful to them. "
