How can I atone for the sins I have committed, such as drinking alcohol, theft from mosques and homes, and mischief; how can I appease my parents after having spent university tuition fees wrongfully; and how can I return to the commitment I once had?

It is recommended to fear Allah, repent sincerely, and not despair of His mercy, for Allah forgives all sins and rejoices in His servant's repentance. Among the expiations for sins is to increase good deeds, especially by observing the obligatory duties and avoiding major sins. What helps in this regard is to change one's accompanying environment to a righteous one, to frequent the mosque, to review one's memorization of the Quran, and to acquire religious knowledge.
