سورة آل عمران

Ali ibn Ibrahim (may Allah have mercy on him): رَّبَّنَا إِنَّنَا سَمِعنَا مُنَادِیًا یُنَادِی لِلإِیمَانِ [Our Lord! surely we have heard a preacher calling to the faith]; that is, the Messenger of Allah (peace be upon him and his family) calls to faith.

Imam Baqir (peace be upon him): The unjust have no Imams to call them by their names. رَبَّنا إِنَّنا سَمِعْنا مُنادِیاً [Our Lord! surely we have heard a preacher]; the caller is the Prophet (peace be upon him and his family).

Imam Sadiq (peace be upon him): And among your supplications after these two rak'ats of the Eid al-Ghadir prayer, let this be: رَبَّنا إِنَّنا سَمِعْنا مُنادِیاً یُنادِی لِلْإِیمانِ أَنْ آمِنُوا بِرَبِّکُمْ فَآمَنَّا ... إِنَّکَ لا تُخْلِفُ الْمیعادَ [Our Lord! surely we have heard a preacher calling to the faith, saying: Believe in your Lord, so we did believe ... indeed, You do not break the promise]; "O Lord! We heard the call and we affirmed the caller, the Messenger of Allah (peace be upon him and his family), when he called out from Your side and conveyed what You revealed to him concerning the wilayah of the guardian of Your command and commanded him to deliver to the people."

Imam Sadiq (peace be upon him), from the supplications of the Day of Ghadir: ... Our Lord! Make our feet firm and cause us to die with the righteous and on their path, while we are Muslims, submitting, and affirming Your awliya (guardians).
