Abu al-Hasan Ali ibn Abi Talib a cousin of Muhammad ibn Abd Allah Prophet of Islam and his brother, from his Family, and one of his companions, was the fourth caliph when year and the first imams in Shia.
Imam Ali had to lead the Muslims to pray Fajr in the mosque of Kufa, during prayer he was beaten by Abdul Rahman Bin mulgim sword poison on his head, and Imam Ali famously said: "I won the Lord of Kaaba," then the poison took his body until he died three days later, specifically on the night of Ramadan, 21 years old in 40 AH at the age of 64.
Tonight is a very tragedic night, filled with tears of depression, and so I'll show you a video of how Shiaa treasured this moment and how tragedic it was.
