It was narrated from ‘Abdur-Rahman bin ‘Awf that he heard

The Messenger of Allah (ﷺ) say:"Allah, may He be glorified and exalted, said: "I am ar-Rahman and 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."
