Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: A man submitted, "O Messenger of Allah! I have some relatives with whom I maintain ties of kinship, but they sever relations with me. I treat them well, but they treat me badly. I deal with them patiently, but they behave ignorantly towards me." The Prophet (peace and blessings be upon him) said: "If the situation is as you describe, then it is as if you are throwing hot ashes upon them, and Allah’s help will continue to be with you as long as you continue doing so."
