What should I do about the bouts of depression that cause apathy in prayer, and about the severe states of sadness that afflict me and make me imagine the grave and God's torment? Is it permissible for me to pray Salatul Tawbah (prayer of repentance) daily with repeated mistakes such as backbiting and gossip, and what is the manner of Salatul Tawbah? What should I do to atone for my transgressions with my fiancé during the engagement period, and how do I know if God is pleased with me?

A Muslim can overcome depression through sincere faith and certainty in Allah, frequent remembrance of Him (dhikr), persistently reciting morning and evening invocations, and the supplication of Dhul-Nun: "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers." The praiseworthy fear of death motivates one to perform good deeds, along with having good expectations of Allah. It is recommended to occupy one's time with reciting the Quran, remembering Allah, and associating with righteous women. The prayer of repentance is recommended; its description is for the worshipper to purify themselves, pray two rak'ahs, and then seek Allah's forgiveness. Repentance nullifies what came before it, and the sign of its acceptance is being guided to perform a good deed after another good deed.
