Four Things We Must Not Lose out on, Whatever Else We Might Lose out on in this Life

The Messenger of Allāh ﷺ said:

Four things, if they’re found in you, don’t give a thought to anything you might come to lose in this world [as a result of retaining them]: truthfulness in speech, protection of trusts, having good character and manners [with people], and keeping away from all that’s prohibited in food [or drink].

Ṣaḥīḥ Al-Jāmiʿ, 873.
