Keep away from that which does not concern you
Abu Hurayrah (radi Allahu anhu) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “It is from the excellence of (a believer’s) Islam that he should shun that which is of no concern to him”
This Hadith lays down a very important principle that one should avoid senseless talk and actions. If one acts upon this principle, he can save himself from many sins and evils.
And Allah Knows Best!
