It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man said: "O Messenger of Allah (peace and blessings be upon him)! I have relatives; I keep ties with them and they cut me off, I am forbearing with them and they behave foolishly towards me, I treat them well and they treat me badly." He (peace and blessings be upon him) said: "If it is as you say, then it is as though you are feeding them hot ashes, and as long as you remain on this course, there will always be with you a helper from Allah against them."
