Sahih al-Bukhari
Good Manners and Form (Al-Adab)
Chapter: Allah will keep good relations with him who keeps good relations with kith and kin
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.
Sahih al-Bukhari 5989
