The Truth Brings Tranquility‏
Assalam Alaikum

The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Leave what puts you in doubt for what does not put you in doubt. The truth brings tranquility while falsehood sows doubt.” [Jami at-Tirmidhi]

Anything that creates doubt in the mind also makes the heart feel uneasy. A believer should only do things that make his heart and soul feel tranquil, at peace and at ease.
