They Have Not Heard the Truth
However, ignorant people disregarded his advice and assassinated Uthman. Imam Ali appointed his sons, after hearing of the plan, Hasan ibn Ali and Husayn ibn Ali (Praise be upon them), to prevent this act, but it was too late; the work was already done. Those ignorant people even accused his Excellency of arranging and preparing this conspiracy. Since that time, such foul acts became prevalent in Islam, and even Imam Ali (Praise be upon him) himself was subjected to this devious and inferior plan of ignorant people. His assassination brought irreparable damage to the world of Islam.
Such is the result of ignorance and wry thoughts that results in deviation.
