Hadith 445
Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "The womb (ties of kinship) is hanging from the Throne, and the one who does good in return for good is not considered as maintaining the ties of kinship. The one who truly maintains the ties of kinship is the person who, when his ties of kinship are severed, still maintains them."
