Riyad us Saliheen: Hadith 330

I heard Messenger of Allah (ﷺ) saying openly not secretly, "The family of so-and-so (i.e., Abu Talib) are not my supporters. My supporter is Allah and the righteous believing people. But they (that family) have kinship (Rahm) with whom I will maintain good the ties of kinship".
