“I heard Al-Ridha (s) say, ‘Whoever says the following supplication when he hears the morning or evening call toprayer and dies on that day or night has died having repented (and will enter Paradise): O my God! I ask Thee on behalf of Thy morning and Thy night, and the voice of Thy callers that You send Blessings upon Muhammad and his Household and that You forgive me as Thee are the Forgiver, the Merciful.’”
