Do Not Die Except in the Condition of Submission

Allah Subhanahu wa ta'ala tells us, don't die except in the condition of submission. If you happen to sin because of human nature, immediately repent to Allah. And don't become too comfortable in sin. A sign of goodness of a human being is regret. When you regret what you did, it shows that you are connected to Allah. You have a good relationship with Allah, your bad deed should make you regret.
