← Previous Hadith "I said: 'O Messenger of Allah, I have a cousin, and I come to him and ask him (for help) but he does not give me anything, and he does not uphold the ties of kinship with me. Then, when he needs me, he comes to me and asks me (for help). I swore that I would not give him anything, nor uphold the ties of kinship with him.' He commanded me to do that which is better and to offer expiation for my oath."
