It is from the excellence of (a believer's) Islam that he should shun that which is of no concern to him.

Abu Hurairah (May Allah be pleased with him) reported:

Messenger of Allah (ﷺ) said, "It is from the excellence of (a believer's) Islam that he should shun that which is of no concern to him".

[At-Tirmidhi].
