How can a servant rebuild his relationship with the Creator and achieve the highest levels of transparency, and can a servant who has committed all abominations and repented return from the path of Satan to the path of faith, and what is the means for Allah to forgive all his sins?

Restoring one's relationship with Allah involves sincere repentance and turning to Him, along with frequent seeking of forgiveness (istighfar), supplication (du'a), and acts of obedience, and abstaining from prohibitions. Allah, the Most High, says: "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'" And His saying: "Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills." Allah transforms the evil deeds of the repentant into good deeds, as He says: "Except for those who repent, believe, and do righteous deeds - for them Allah will change their evil deeds into good ones. And ever is Allah Forgiving and Merciful."
