Shab-e-Zarbat (night of 19th Ramadan) or Night of attack on Imam Ali (as) at Kufa Mosque
On the 19th of the month of Holy Ramadan (Mah e Ramzan) of the year 40 A.H, Imam Ali (as) came to the mosque in Kufa for his morning prayers. Imam Ali (as) gave the call for prayer (Azaan) and became engaged in leading the congregation. Abd-al-Rahman ibn Muljam pretending to pray, stood just behind Imam Ali (as), and when Imam Ali (as) was in a state of prostration, Abd-al-Rahman ibn Muljam dealt a heavy stroke with his sword, inflicting a deep wound on Imam Ali’s (as) head.
This was the time when Imam Ali (as) uttered his famous words : “Fuzto warab-il-Kaaba” – “By the Rab of Kaaba, I am successful”. Holy Prophet Muhammad (saww) had prophesied the assassination of Imam Ali (as) and his issues. Regarding Imam Ali (as) Holy Prophet Muhammad (saww) had said, “O Ali! I see before my eyes thy beard dyed with the blood of thy forehead.” They assassinated Imam Ali (as) at his finest time – the hour of standing before Allah, the Exalted, during a prayer of submission, in the best of days, while fasting during the month of Ramadan (Mah e Ramzan); during the most glorious Islamic duties, while preparing to wage jihad, and in the highest and most pure divine places, the Mosque of Kufa.
