It was narrated from Ibraheem bin "Abdullah bin Qariz that his father told him that

he entered upon ‘Abdur-Rahman bin "Awf when he was sick. ‘AbdurRahman said to him: May your relatives uphold ties of kinship with you. The Prophet (ﷺ) said: "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 break ties with him and cut him off.”
