Abdullah Ibn Sinan says that I pleaded to Imam Ja’far as-Sadiq (a.s.), “I have a cousin, I do Silet ar-Rahm (kindness) towards him and do not wish to break ties with him. But he wants to break ties with me. (Master!) I want to maintain relations but he wishes to sever them. Due to this behaviour of his I am also inclined to cut off ties with him. Can you permit me to do so?”
Imam (a.s.) replied:
“(Remember) If you behave kindly with this relative of yours inspite of his Qat’a ar-Rahm (then it is possible that one day this will affect him and he too will begin to fulfill his obligations). In this way the Mercy of Allah shall be upon both of you. But if you break ties with this cousin of yours then neither of you shall be eligible for the Mercy of Allah.”( Al – Kafi )
