The one who is forgiven, are his sins erased from his scrolls?
Yes, they are erased, if Allāh forgives him, he erases them for him.
(يَمْحُوا۟ ٱللَّهُ مَا يَشَآءُ وَيُثْبِتُۖ وَعِندَهُۥٓ أُمُّ ٱلْكِتَٰبِ)
“Allah blots out what He wills and confirms (what He wills). And with Him is the Mother of the Book (Al-Lawh Al-Mahfūdh)” [Ar-Ra’d, 39]
(فَأُو۟لَٰئِكَ يُبَدِّلُ ٱللَّهُ سَيِّـَٔاتِهِمْ حَسَنَٰتٍۗ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا)
“For those, Allah will change their sins into good deeds, and Allah is Oft-Forgiving, Most Merciful.” [Al-Furqān, 70]
So they are erased. His statement ‘forgive’, it (means) covering and erasing and removing.
(قُلْ يَٰعِبَادِىَ ٱلَّذِينَ أَسْرَفُوا۟ عَلَىٰٓ أَنفُسِهِمْ لَا تَقْنَطُوا۟ مِن رَّحْمَةِ ٱللَّهِۚ إِنَّ ٱللَّهَ يَغْفِرُ ٱلذُّنُوبَ جَمِيعًاۚ إِنَّهُۥ هُوَ ٱلْغَفُورُ ٱلرَّحِيم)ُ
“Say: “O ‘Ibādi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allāh, verily Allāh forgives all sins. Truly, He is Oft-Forgiving, Most Merciful.” [Az-Zumar, 53]
And the black thawb is more concealing of stains, so it includes covering and erasing.
If Allah forgives him, He covers it for him and erases it. And he will not be held to account for it nor will it be recorded from his bad deeds.
( فَمَحَوْنَآ ءَايَةَ ٱلَّيْلِ وَجَعَلْنَآ ءَايَةَ ٱلنَّهَارِ مُبْصِرَة)
“Then, We have made dark the sign of the night while We have made the sign of day illuminating.” [Al-Isrā, 12]
Ya’nī the sign of the night went and was erased.
