From Sahih Muslim (Hadith 6536):
Abu Huraira reported Allah's Messenger (ﷺ) as saying:Avoid suspicion, for suspicion is the gravest lie in talk and do not be inquisitive about one another and do not spy upon one another and do not feel envy with the other, and nurse no malice, and nurse no aversion and hostility against one another. And be fellow-brothers and servants of Allah
