Fajr prayer
Ali was assassinated by Kharijites in 661. On the 19th of Ramadan, while Praying in the Great Mosque of Kufa, Ali was attacked by the Kharijite Abd-al-Rahman ibn Muljam. He was wounded by ibn Muljam's poison-coated sword while prostrating in the Fajr prayer. When Alī was assassinated, Muawiyah had the largest and the most organized and disciplined force in the Muslim Empire.
