Fajr prayer
On January 26, 661, while praying in the Great Mosque of Kufa, Ali was attacked by Abd al-Rahman ibn Muljam. He was wounded by ibn Muljam's poison-coated sword while prostrating during the Fajr prayer. Medical treatment for Ali was undertaken by Atheer bin Amr As-Sakooni, a leading physician; however, Ali succumbed to his injuries on January 28, 661.
