Hadith 442
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) said: "The word 'Rahm' (kinship) is derived from 'Rahman' (the Most Merciful). It is hanging from the Throne and says: O my Lord! I have been cut off. I have been wronged. So its Lord says to it: Are you not pleased that I will cut off the one who cuts you off, and I will join the one who joins you?"
