It is narrated from Ibrahim bin Abdullah bin Qariz (may Allah have mercy on him) that his father went to visit Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) in his illness, and Sayyiduna Abd al-Rahman (may Allah be pleased with him) said to him: "The tie of kinship has brought you (here). I heard the Messenger of Allah (peace and blessings be upon him) say: 'Allah Almighty says: I am al-Rahman and this is the rahim; I derived its name from My name. So whoever joins it, I will join him, and whoever cuts it, I will cut him off.'" Or he said: "Whoever cuts it off completely, I will cut him off completely."
