“The word ‘Ar-Rahm’ (womb is called ‘raham’ in Arabic) derives its name from Ar-Rahman. And Allah said: ‘I will keep good relation with the one who will keep good relation with you (i.e. with Ar-Rahm), and I will sever the relation with him who will sever the relation with you.” – (#5988, Bukhari)
Allah is speaking first and foremost to the womb of Hawwa, who is the mother of all of humanity. Hers is the womb – the raham – from which all humanity has emerged – including me, and you, as well as those whom you consider your enemy.
Allah Ar-Rahman will keep good relation with the one who keeps good relations with the raham of (i.e. the progeny of) Hawwa, and Allah Ar-Rahman will sever relation with the one who will sever relation with the raham of (i.e. the progeny of) Hawwa.
