It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "The womb (ties of kinship) is suspended with the Throne. The one who only reciprocates is not truly upholding the ties of kinship; the true upholder of kinship is the one who maintains relations even when others sever them."
