Another responsibility is to recite Du’a al-Nur1. This supplication has been narrated from the A`immah of the Ahlul Bayt (as) and is a prayer which is found in many of the reliable books of supplication.
It has been narrated that Imam Ja’far b. Muhammad as-Sadiq (as) said: “Any person who makes a promise with Allah with this du’a for forty mornings will be among the helpers of our Qa`im (ajtf).
If that person is to die before the return of the Imam, then Allah the High will bring him forth from his grave (to help the Imam). For every letter of this pact, one thousand good deeds will be written in the person’s book of records and one thousand sins will be erased.”2
This supplication has been mentioned in responsibility forty-eight.
