My father narrated to us. He said: Sa`d b. `Abdullah narrated to us from Muhamad b. `Isa from `Abbas the servant of al-Rida from Abi’l Hasna al-Rida from his father . He said: Abu `Abdillah al-Sadiq would say:

Whoever says, when he hears the call to the morning prayer: “O Allah! I ask You by the commencement of Your day, the maintenance of Your night, the attendance of those praying to You, and the voices of those supplicating to You, to forgive me. Surely, You are the Forgiving, the Merciful (allahumma inni as’aluka bi iqbali naharik, wa idbari laylatik, wa huduri salatik, wa aswati du`a’ik an tatub `alay, innaka anta ‘tawab al-rahim)” – whoever says that [when he hears the call to the morning prayer or] when he hears the call to Maghrib prayer and dies on that day or on that night, he will be forgiven.
