The scholar Abu Ali Hasan bin Mohammad Al-Tousi narrated From his blessed father the scholar Abilaafar Al-Tousi, from the scholar Abu Abdillah Mohammad bin Mohammad bin No’man, from Abu Ghalib Ahmad bin Mohammad Al-Zarari, from Abul Husain Ali bin Sulaymaan bin Juham, from Abu Abdillah Mohammad bin Khaid Al-Tayalesi, from Alaa’ bin Razin, from Mohammad bin Muslim Al-Thaqafi, who said:
I asked ABA JAAFAR MOHAMMAD BIN ALI (ASWS) about the verse, “...ALLAH (SWT) will change their evil deeds to good deeds. ALLAH (SWT) is oft-forgiving, merciful.”(25:70)
Abu Jaafar (ASWS) replied:
On the Day of Judgement, believers with sins will be brought on the stand of judgement, and ALLAH (SWT) himself will undertake their judgement, so no one can see it. Then ALLAH (SWT) will show him (the believer) his sins to which he will admit. Then ALLAH (SWT) will tell the clerks to change his evil deeds to good deeds, and to show it (his book) to the people.
When the people will see his book, they will say, “This slave did not even have one sin.”
Then ALLAH (SWT) will order that the slave be taken to Paradise. This is the TA’WEEL(inner meaning) of this verse, and it applies specifically to our Shia who have committed sins.
(Ref :Amaali of Tousi 1:70, Behar Al-Anwar 7:261 and 68:100)
