Abu ‘Abdu’r-Rahman ‘Abdullah ibn Mas’ud reported that a man said, “Messenger of Allah, I have some relatives with whom I maintain relations but they cut me off. I am good to them and they are bad to me. I am forbearing to them and they are impatient towards me.” He said, “If you are as you have said, then it is as if you are giving them hot embers to drink. You will continue to have a helper from Allah against them as long as you remain doing that.” [Muslim]
