You who believe, be steadfast in your devotion to God and bear witness impartially: do not let hatred of others lead you away from justice, but adhere to justice, for that is closer to awareness of God. Be mindful of God: God is well aware of all that you do.
#Quran 5:8
Ar-Rahm' (womb) derives its name from 'Ar-Rahman' (i.e. Allah). So whoever keeps good relations with it (i.e. Kith and kin), Allah will keep good relations with him, and whoever will sever it (severs bonds of Kith and kin) Allah too will sever His relations with him.
[Bukhari]
