The Cause of the Killing of 'Umar ibn al-Khattab (may Allah be pleased with him) and What Happened Afterward

Question:
We will add to it. The Honorable Shaykh says: We hope that you will provide a brief account of the main cause of the killing of 'Umar ibn al-Khattab (may Allah be pleased with him), who killed him, and how the events unfolded after his killing?

Answer:
I heard this during the lesson that it was a gang that gathered from the followers of the Jewish Ibn Saba. They besieged him in his house under the pretext that they wanted to negotiate with him. This was during the season of Hajj, and the people were in Hajj; they had gone for Hajj, and those present understood that the matter was one of negotiation with the Caliph and a review of the situation with the Caliph. They did not realize that there was treachery in it. When it was night, they climbed over the wall and killed him. So they did not come to negotiate as they claim, nor did they come to review the situation, but rather they came to kill them. May Allah curse them and disgrace them. Yes.
