The dawn prayer is a general title for prayers that are recited at the dawn of Ramadan. The most famous of them is the prayer that Imam Reza (AS) has quoted from Imam Baqir (AS) and begins with the phrase "Allah إني أني أنسْ بَهَائِكَ بِأَبْهَاهُ وَلُّ باَهَيَكَ". The dawn prayer is also known as the Bahا'. Prayer. The dawn prayer is the prayer of Imam Baqir (as) in the dawn of Ramadan. My father quoted his grandfather Imam Baqir as saying: "The great name of God is in this prayer. So whenever you pray, strive in prayer; Because it lies in knowledge and hide it from others except its people. "The hypocrites, the deniers, and the deniers are not its people, and this is the prayer of Mubahala."
