Hazrat Muhammad (ﷺ) said: “The biggest deed according to Allah is polyteism, and then to abandon relationships.” (Sahih al-Jaame-o Al-Saghir, raqam: 166)
Help Your Brother: Hazrat Anas (رضی اللہ عنہ) quotes that Hazrat Muhammad (ﷺ) said: Help your brother, even if he is an oppressor or oppressed. It was said, O Prophet of Allah (ﷺ)! We can help the oppressed, but how can we help the oppressor? He (ﷺ) said: By holding the hand of the oppressor (so that he refrains from oppression) (Bukhari). Hazrat Abu Huraira (رضی اللہ عنہ) says that a person said, O Prophet of Allah (ﷺ)! I have a few relatives, I try to reconcile with them and they break relationships with me. I do them favors and they respond badly about that. I try to act with tolerance and they act with ignorance. Hazrat Muhammad (ﷺ) said, if you definitely do this then you put burning ash on their faces. And there will always be an angel with you from Allah who will always keep you dominant over them till the time you maintain this state of affairs.
