On the last day of Safar in 203 AH, Imam Reza died. Imam Reza was buried beside the caliph's grave. Following the death of Imam Reza a great revolt took place in Khurasan, Persia. Al-Ma’mun wept and mourn for Imam Reza and tried to show himself innocent of the crime. But for all he did, he could not get himself acquitted and prove his innocence. Al-Ma'mun wrote to Hasan ibn Sahl, his governor in Iraq, the Hijaz, etc. informing him of his grief on the Imam's death. The governor fell ill and al-Ma'mun appointed Dinar ibn Abdallah to replace him. Some of Ibn al-Mahdi's commanders deserted him, and he died.

Mihna
The Mihna refers to a test instituted by the Abassid Caliph al-Ma'mun in 218 AH/833 AD, in which religious scholars were required to answer whether or not the Qu'ran was a created text. Those who answered in the affirmative were retained; those who answered in the negative were dismissed...

, which was initiated in 833, only four months before he died.

The 'mihna', is comparable to Medieval European inquisitions only in the sense that it involved imprisonment, a religious test, and a loyalty oath. The casualties of 'Abbasid inquisition would not approach a fraction of those executed in Europe under similar circumstances. This is because the people who were subject to the mihna were traditionalist scholars whose social influence and intellectual quality was uncommonly high. Al-Ma'mun introduced the mihna with the intention to centralize religious power in the caliphal institution and test the loyalty of his subjects. The mihna had to be undergone by elites, scholars, judges and other government officials, and in consisted of a series of questions relating to theology and faith. The central question was about the createdness of the Qur'an, if the interrogatee stated he believed the Qur'an to be created, he was free to leave and continue his profession.

The controversy over the mihna was exacerbated by al-Ma'mun's sympathy for Mu'tazili

Al-Ma'mun also attempted to divorce his wife during his reign, who had not borne him any children. His wife hired a Syrian judge of her own before al-Ma'mun was able to select one himself; the judge, who sympathized with the caliph's wife, refused the divorce.

Most Shi'ites realized, however, that ar-Rida was too old to survive him and saw al-Ma'mun's gesture as empty; indeed, ar-Rida died in 818. The incident served to further alienate the Shi'ites from the Abbasids, who had already been promised and denied the Caliphate by al-'Abbas.

Personal Characteristics

Al-Tabari (v. 32, p. 231) describes al-Ma'mun as of average height, light complexion, handsome and having a long beard losing its dark colour as he aged. He relates anecdotes concerning the caliph's ability to speak concisely and eloquently without preparation, his generosity, his respect for Muhammad and religion, his sense of moderation, justice and his love of poetry.

Death

Al-Tabari (v.32, pp. 224–231) recounts how Al-Ma'mun was sitting on the river bank telling those with him how splendid the water was. He asked what would go best with this water and was told a specific kind of fresh dates. Noticing supplies arriving, he asked someone to check whether such dates were included. As they were, he invited those with him to enjoy the water with these dates. All who did this fell ill. Others recovered. But Al-Ma'mun died. As he was dying he spoke, expressing his belief in the unity of God and his reliance on God's mercy. He encouraged his successor to continue his policies and not burden the people with more than they could bear. This was on August 9, 833.
