It was narrated that Abu Salamah said:

Abdur-Raddad fell sick and "Abdur-Rahman bin "Awf visited him. Abur-Raddad said: The best of them and the one who most upholds ties of kinship, as far as I know, is Abu Muhammad. "Abdur-Rahman bin "Awf said: I heard the Messenger of Allah (ﷺ) say: "Allah, may He be glorified and exalted, said: "I am Allah and I am ar-Rahman. I have created ar-rahim (ties of kinship) and have derived its name from My name. Whoever upholds ties of kinship, I will uphold ties with him and whoever breaks ties of kinship, I shall cut him off.“
