Leave what you doubt for what you do not doubt; indeed, truthfulness is tranquility, and lying is doubt

Explanation

The Prophet (may Allah's peace and blessings be upon him) commanded that one should leave whatever words or deeds he has doubts about, whether they are prohibited or not, unlawful or lawful, and choose instead what is not doubtful—things whose goodness and lawfulness he is certain about, as such things bring tranquility and comfort to the heart, whereas whatever is doubtful sows anxiety and confusion in the heart.

Lessons
