Chapter 46: The Book of Virtue, Enjoining Good Manners, and Joining of the Ties of Kinship
Abu Huraira reported Allah' s Messenger (ﷺ) as saying. Don' t nurse malice against one another, don' t nurse aversion against one another and don' t be inquisitive about one another and don' t outbid one another (with a view to raising the price) and be fellow-brothers and servants of Allah.
Sahih Muslim 2563c
