Is it true that if a Muslim disobeys Allah for years then repents with sincere repentance, their repentance is immediately accepted, their sins are erased, their evil deeds are turned into good deeds, the veil between them and Allah is lifted, they become a friend of His, their prayers are answered, they achieve humility in prayer, and they enter the highest Paradise if they die?

"One who repents from sin is like one who has no sin, and Allah accepts his repentance and forgives him, as He Almighty said: ﴿And it is He who accepts repentance from His servants and pardons sins.﴾ Every pious believer is a friend (wali) of Allah according to the measure of his faith and piety, and a repentant person may fall into this category if he achieves piety. As for the changing of evil deeds into good deeds, this change may occur on the Day of Resurrection, as mentioned in the hadith of Abu Dharr. The repentant person should strive to purify his heart and attain humility in prayer. Entry into the highest paradise (Firdaws al-A'la) is not guaranteed for every repentant person, for the varying ranks of Muslims in Paradise depend on the varying degrees of their faith and good deeds, and Firdaws al-A'la is for those who have fulfilled the conditions of faith and righteous deeds mentioned in the Quran."
