(13) باب مَنْ وَصَلَ وَصَلَهُ اللَّهُ
Narrated `Aisha:
(the wife of the Prophet) The Prophet (ﷺ) said, "The word 'Ar-Rahm' (womb) derives its name from 'Ar- Rahman' (i.e. Allah). So whosoever keeps good relations with it (womb i.e. Kith and kin), Allah will keep good relations with him, and whosoever will sever it (i.e. severs his bonds of Kith and kin) Allah too will sever His relations with him.
