Abu Hurairah (May Allah be pleased with him) reported:
A man said to Messenger of Allah ﷺ: "I have relatives with whom I try to maintain good relationship but they sever relations with me; whom I treat kindly but they treat me badly, with whom I am gentle but they are rough to me." He ﷺ replied, "If you are as you have said, then it is as though you are feeding them hot ashes and you will not be without a supporter against them from Allah, as long as you do so."
وعن أبى هريرة رضي الله عنه أن رجلاً قال: يا رسول الله إن لى قرابة أصلهم ويقطعونى، وأحسن إليهم ويسيئون إلى، وأحلم عنهم ويجهلون على! فقال: “لئن كنت كما قلت فكأنما تسفهم المل ولا يزال معك من الله تعالى ظهير عليهم ما دمت على ذلك” ((رواه مسلم)) وقد سبق شرحه في “باب صلة الأرحام”.
