Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, “It is from the excellence of (a believer’s) Islam that he should shun that which is of no concern to him”.
Commentary: This hadith lays down a very important principle that one should avoid senseless talk & action. If one acts upon this principle, he can save himself from many sins & evils. [Riyadh-us Saaliheen
Book 01, Chapter 05, Hadith 67].
In addition, it can save one alot of time because many things that we talk about we find out it is of no importance in regards to the progress of lives. And it is through such that we mostly fall into the sin of backbiting & uncovering faults.
We ask Allah (swt) keep us aware from all things that do not concern us, ameen.
