Neither nurse mutual hatred, nor jealousy, nor enmity, and become as fellow brothers and servants of Allah. It is not lawful for a Muslim that he should keep his relations estranged with his brother beyond three days.
Sahih Muslim Book 45, Hadith 26
← Previous Hadith Allah's Messenger, I have relatives with whom I try, to have close relationship, but they sever (this relation). I treat them well, but they treat me ill. I am sweet to them but they are harsh towards me. Upon this he (the Holy Prophet) said: If it is so as you say, then you in fact throw hot ashes (upon their faces) and there would always remain with you on behalf of Allah (an Angel to support you) who would keep you dominant over them so long as you adhere to this (path of righteousness).

Sahih Muslim Book 45, Hadith 25 Next Hadith → Anas b. Malik reported Allah's Messenger (ﷺ) as saying like this. This hadith has been narrated through another chain of transmitters.
