This is how to repent in Islam: give up the sin straight away, regret what has happened in the past, resolve not to go back to sinning, restore people’s rights or property, and repent before the agony of death is upon you.

Forgiveness means seeking protection from the evil of what is past, and repentance means returning to Allah and seeking protection from the evil of one’s own bad deeds which one fears may lie ahead in the future.
