Fajr prayer
Holy Du'ā (archaically transliterated "Doowa") is the mandatory Nizari Isma'ili prayer recited three times a day: Fajr prayer at dawn, Maghrib prayer at sundown and Isha prayer in the evening. Each Holy Du'a consists of 6 rakat, totaling 18 per day, as opposed to the 17 of Sunni and Twelver salat ("namaz").
