Qais narrates that Hazrat Umar (may Allah be pleased with him) said: "You do not inform me about these two stations of yours, but even so, I will ask you and I will discern from your faces which station is better." He says that Jarir submitted to him: "O Commander of the Faithful! I will tell you. One station, in terms of trees, is close to the land of the Arabs, and the other station is in the land of Persia, where there is severe fever, heat, and bedbugs, that is, Mada'in." He says that Hazrat Ammar contradicted him and said: "You have lied." Hazrat Umar (may Allah be pleased with him) said: "You have lied even more than him." Then Hazrat Umar (may Allah be pleased with him) said: "Tell me about this leader of yours, is he a reasonable and suitable man?" The people said: "By Allah! He is neither one who does good deeds, nor one who is sufficient on his own, nor does he know politics." So he removed him from office and sent Hazrat Mughirah bin Shu'bah (may Allah be pleased with him).
