Abū ‘Abdillāh (Imam Sādiq (a.s.)) said: The least that a Zā`ir of Ḥusain (a.s.) gains is that every good deed will be registered as one million good deeds for him and every bad deed will be registered as (only) one. And how can one be compared to a million?! The Imam (a.s.) added: O Safwān! Rejoice, for verily Allāh has some angels who carry rods made of light and when the Keepers are about to register a bad deed for the Zā`ir of Ḥusain (a.s.), these angels tell the Keepers to stop. Therefore, the Keepers will not register the bad deed. However, once the Zā`ir performs a good deed, these angels tell the Keeper, “Register now! ‘They are the ones whom Allāh changes their bad deeds to good deeds” (25:70).
