Do you want to have peace of mind, reassurance, and joy? You should ask for the forgiveness of Allah, The Almighty.
Allah (Subhanahu wa ta'ala), Says (what means):
“Seek Forgiveness of your Lord and repent to Him, [and] He Will Let you enjoy a good provision}
[Surat al-Hud | C.11 : V.3]
The Prophet ﷺ say: ‘Whoever says: “I seek forgiveness from Allah, the Magnificent, whom there is none worthy of worship but Him, the Living, Al-Qayyum, and I repent to him,”
(Astaghfirullāhal-`Aẓīm alladhī lā ilāha illā huwal-Ḥayyul-Qayyūmu wa atūbu ilaih)
then Allah will forgive him, even if he fled from battle”
[Sahih At-Tirmithi: 3577]
