[Machine] Ali was critical of Umar one day when the people of Najran came to him. Ali wrote the book between the people of Najran and the Prophet ﷺ , and they increased in number during Umar's reign until he feared them and they disagreed with each other. They came to Umar and asked him for a replacement, so he replaced them. Then they regretted it and put something between them, but Umar refused to remove them. When Ali became the caliph, they came to him and said, "O Amir al-Mu'minin, your intercession with your words and your writing." Ali said, "Woe to you! Umar was a wise ruler."
