Muhammad b. Muslim AI Saqafi narrates: I asked Abu Jafar Muhammad b. Ali (a.s.) about the verse, “ ..Allah will change their evil deeds to good deeds. Allah is oft-forgiving, merciful” (Surah Furqan (25):70).

Imam (a.s.) replied: On the Day of Judgement, believers with sins will be brought on the stand of judgement, and Allah himself will undertake their judgement, so no one can see it. Then Allah will show him (the believer) his sins to which he will admit. Then Allah 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 a single sin.

Then Allah will order that the slave be taken to Paradise. This is the Taaveel (actualization) of this verse, and it applies specifically to our Shia who have committed sins.
