Umar had already dispatched al-Jarrah ibn ʿAbd Allah al-Hakami to take charge of Khurasan in his place. Around that time Yazid ibn al-Muhallab’s son—Makhlad ibn Yazid—appeared and said:
“O Commander of the Faithful, Allah—exalted is He—has favoured this community by making you its guardian; do not let us become the most wretched of people because of you. Why, then, do you keep this elderly man confined when I stand ready to assume whatever settlement you require on his behalf?”
Umar replied, “I will not reach a settlement with you unless you undertake the entire sum that is being demanded of him, and I will accept from him nothing less than all the Muslim wealth in his possession.”
Makhlad responded, “O Commander of the Faithful, if you have proof for what you allege against him, produce it; otherwise, accept his oath or make peace with me on his behalf.”
Umar answered, “I will take from him nothing short of everything he holds.”
Makhlad ibn Yazid then left ʿUmar’s presence (1), and not long thereafter Makhlad died. Umar used to say, “He was better than his father.”
Umar subsequently ordered that Yazid ibn al-Muhallab be dressed in a coarse woollen cloak and sent on a camel to the island of Dahlak (2), the place to which wrongdoers were exiled. Intercession was made for him (3), so he was returned to prison, where he remained until ʿUmar ibn ʿAbd al-ʿAziz fell ill—may Allah have mercy on him (4).
In that same year, during Ramadan, ʿUmar ibn ʿAbd al-ʿAziz dismissed al-Jarrah ibn ʿAbd Allah al-Hakami from the governorship of Khurasan, after one year and five months in office. He removed him because al-Jarrah had been collecting the jizya from non-Muslims who accepted Islam, saying, “You are only embracing Islam to evade it.” (5) As a result, they refrained from entering Islam, remained upon their religion, and continued to pay the jizya.
Umar wrote to him: “Allah only sent Muhammad ﷺ as a caller to the truth; He did not send him as a tax-collector.” He therefore dismissed him and appointed in his place ʿAbd al-Rahman ibn Naʿim al-Qushayri (6) over military affairs and ʿAbd al-Rahman ibn ʿAbd Allah over fiscal revenues (7).
That year Umar also wrote to his governors, commanding them to do good and forbidding them from evil, clarifying the truth for them, honouring them in his correspondence, and warning them of Allah’s might and retribution.
Among what he wrote to ʿAbd al-Rahman ibn Naʿim al-Qushayri was the following:
“To proceed: Be a servant who sincerely advises Allah’s creatures, and let not the blame of any blamer deter you concerning Allah. Allah’s claim upon you is greater than that of the people, and His right over you is weightier. Do not appoint to any office over the Muslims except one who is known for sincere counsel toward them and for gentleness with them.”
