Abd Allah al-Ma'mun ibn Harun al-Rashid

عبد الله المأمون بن هارون الرشيد

Abbasid caliph, given the oath of allegiance at Baghdad after the deposition of his brother al-Amin in 196 AH 1; he died in 218 AH 2. Al-Tabari also records the mihna over the Qur'an in his reign 3. According to al-Suyuti, he was born on the night of Saturday, fourteen days before the end of Rabi' I 170, the night his paternal uncle al-Hadi died and his father's accession was made; there was no other night in all time in which one caliph died, another rose, and a child was born, except this one 4. Also according to al-Suyuti, in 204 he set out and entered Baghdad in Safar, where the Abbasids asked him to return to black, the Abbasid colour, and he agreed; in 218 people were tested on the doctrine that the Qur'an was created 5. He alone, after Uthman ibn Affan (may God be pleased with him), is said to have memorised the Qur'an among the caliphs, and his seal bore the inscription 'Abd Allah ibn Ubayd Allah'. A woman asked him about the division of an inheritance of 600 dinars; he reckoned it out: two daughters take two-thirds, a mother a sixth, a wife an eighth, and twelve brothers received two dinars each while she received one dinar, and it came out as he had said 6. Also according to al-Suyuti, a Kharijite came to him and asked what had moved him to oppose them; he answered with a verse of God's Book, and when asked whether he knew it was revealed he said yes, and when asked for proof he gave the consensus of the community. The Kharijite replied: 'As you accepted their consensus on the revelation, accept their consensus on the interpretation.' The Kharijite said, 'You have spoken truly,' and addressed him as Commander of the Faithful. The first hadith he transmitted from a pulpit set up for him was, through Hushaym, Abu al-Jahm, al-Zuhri, Abu Salama and Abu Hurayra (may God be pleased with him): 'Imru' al-Qays, banner-bearer of the poets, to the Fire' 7. According to al-Mas'udi, at the start of his career, while al-Fadl ibn Sahl dominated him, al-Ma'mun engaged in judging by the stars, followed the ways of the Sasanian kings such as Ardashir ibn Babak, and laboured at reading ancient books. When he came to Iraq he gave this up, professed divine unity and the promise and the threat, sat with the theologians, and favoured the disputatious ones such as Abu al-Hudhayl al-Allaf and Ibrahim ibn Sayyar al-Nazzam. He kept jurists and men of letters attending his council and paid them stipends, so that each party wrote books defending its school. He was the most forgiving of people, the most patient, and the most generous with money 8. Also according to al-Mas'udi, al-Rashid said of him: 'I recognise in Abd Allah the firmness of al-Mansur, the piety of al-Mahdi, and the dignity of al-Hadi.' After al-Asma'i had recited to them, a prophecy was made concerning the two of them, that their word would be scattered, blood would be shed and the veils of women torn. Al-Rashid gave him war and the son of his own mother peace, and said: 'We fear your son for Abd Allah, and we do not fear Abd Allah for him' 9. His mother was from Badhghis, named Marajil. Al-Fadl ibn Sahl dominated him and pressed him over a slave-girl he wished to buy, and he killed him, though some claimed that someone had been secretly sent against him to kill him. He showed Shi'i leanings and lampooned his paternal uncle Ibrahim ibn al-Mahdi, nicknamed Ibn Shakla, in verse; Ibrahim answered him in verse. He used to say that everything could be forgiven except disparaging the kingship, disclosing secrets and violating the sanctity of women, and that the masters of people in this world are the generous and in the next the prophets. He addressed the estates of his family, citing a verse of the Qur'an. He died at al-Budandun, near Ayn al-Qushayra, in 218 AH, aged 49, and was buried at Tarsus 10. More remarkable still was the man who broke wind during his address: al-Ma'mun said of him, 'I have never seen a man steadier of heart,' and gave him fifty thousand dirhams. He said to Abu al-Atahiya: 'The nature of the soul is boredom and the love of novelty' 11. Al-Suli related from Ya'qub ibn Ja'far, as in al-Mas'udi, the reason for his wearing green and then black: the Hashimites gathered before Zaynab bint Sulayman ibn Ali, the most senior of the Abbasid line in descent, and she spoke to him. He answered her: 'O aunt of the Messenger of God ﷺ, when he died Abu Bakr succeeded, then Umar, who did not go beyond the practice of those before him; then Uthman, who turned to the Umayyads; then the matter came to Ali ibn Abi Talib (may God be pleased with him), who appointed Abd Allah ibn al-Abbas to Basra, Ubayd Allah ibn al-Abbas to Yemen, and Qutham to Bahrain, and he left none of them without an office. So this debt stayed upon us until his offspring sufficed us.' Then he returned to wearing black. He also had a poem fitting the theme, including the line: 'Am I to be blamed for giving thanks to the legatee, Abu al-Hasan?' 12.

Al-Ma'mun was an Abbasid caliph of the ninth century, son of Harun al-Rashid. He loved learning and books, and translation flourished at the House of Wisdom in Baghdad in his reign — which also saw the Mihna that tested the scholars. He ruled about twenty years and died in 833 CE.

Abd Allah al-Ma'mun ibn Harun al-Rashid, seventh Abbasid caliph (198–218 AH / 813–833 CE), took power after his brother al-Amin was deposed and died in the brothers' civil war; he ruled from Merv before returning to Baghdad. His reign is famous for the translation movement at the House of Wisdom and for patronage of philosophy, astronomy and geography, including the celebrated measurement of the earth. On its other side was the Mihna: he imposed the Mu'tazili doctrine of the created Qur'an as a test on judges and scholars, and Ahmad ibn Hanbal was jailed for refusing — an episode Sunni memory reads as state intrusion into belief. Al-Ma'mun died at Tarsus in 218 AH; his brother al-Mu'tasim succeeded him.

Abd Allah al-Ma'mun ibn Harun al-Rashid (198–218 AH / 813–833 CE), seventh Abbasid caliph, was acclaimed after the deposition of his brother al-Amin in the civil war that besieged Baghdad; he stayed in Khurasan for years before returning to Baghdad in 204 AH. His reign is bound to the height of the translation movement: the House of Wisdom became the centre of rendering Greek, Persian and Sanskrit works, and the caliph patronized scientific projects like the measurement of the earth's circumference at Sinjar and the verification of astronomical tables, and is remembered loving debate and the sessions of the mutakallimun. On the same coin of state power was the Mihna: in 218 AH, shortly before his death, al-Ma'mun imposed on the judges the Mu'tazili declaration of the created Qur'an and tested the scholars on it; Ahmad ibn Hanbal resisted and was punished under al-Mu'tasim, who continued the policy — in Sunni memory the emblem of the state's quarrel with the fuqaha. Al-Ma'mun died on campaign at Tarsus in 218 AH and his brother Abu Ishaq al-Mu'tasim succeeded; his era stands in history as both the height of early Abbasid civilization and its doctrinal crisis.

Overview

Abd Allah al-Ma'mun ibn Harun al-Rashid, an Abbasid caliph. He was given allegiance in Baghdad after the deposition of his brother al-Amin in 196 AH, and died in 218 AH. 1 2 Al-Tabari mentions the Mihna of the Qur'an in his reign. 3

His upbringing and affair

Al-Suyuti says that he was born on the night of the death of his uncle al-Hadi and the allegiance of his father, in 170 AH. 4 Al-Mas'udi says that al-Rashid said of him that he recognised in him the firmness of al-Mansur and the asceticism of al-Mahdi, and that his mother was a Badhghisi woman called Maraji. 9

Al-Mas'udi says that at the start of his affair, when al-Fadl ibn Sahl had the upper hand over him, he leaned toward considering astrological judgements. When he came to Iraq he gave that up, sat with the theologians, favoured the disputants, and kept the jurists and men of letters in his session, paying them their stipends. He describes him as the most forgiving of people and the most generous with money. 8

His caliphate

Al-Suyuti says that he marched in 204 AH and entered Baghdad in Safar, and that in 218 AH he tested the people with the doctrine that the Qur'an was created. 5 He says that among the caliphs only Uthman ibn Affan and al-Ma'mun had memorised the Qur'an. 6

Al-Mas'udi says that he died at al-Badidun, at the spring of al-Qushayra, in 218 AH at the age of forty-nine, and was buried in Tarsus. 10

Harun al-Rashid

Harun ibn Muhammad al-Mahdi, fifth Abbasid caliph; in al-Baladhuri: as prince he led the summer raid of year 163 for his father, besieging Damalu and granting its people aman — settled at Baghdad's Samalu quarter — and in year 165 descending on the Gulf, repairing Masisa and its mosque, increasing its garrison and building the Adhana-bridge palace on the Sayhan; as caliph he learned in year 171 that the Byzantines had conspired to fortify Tarsus and forestalled them through Harthama ibn A'yan and Faraj ibn Sulaym, settling the two levies, ordered Ayn Zarba built and fortified in year 180 and the city of the Black Church likewise, named the march cities the 'Awasim, returned the Cypriot captives taken by Hayy ibn Ma'yuf, restored Filastin's deserted estates to their people through Harthama with the takhafif and rudud, disbursed funds through the marches and coasts, and carried the craft of raiding, in Mu'awiya ibn Amr's words, to a pitch unmatched before him. Tarikh Baghdad (#7347): born at Rayy three nights short of Dhu'l-Hijja 150 (another report 149), given the bay'a at Baghdad on Friday 14 Rabi' I 170 — the very day al-Hadi died — aged nineteen years, two months and thirteen days, with al-Ma'mun born that same night; he kept al-Khuld, alternated a year of hajj with a year of ghazw, took a hundred scholars and their sons on pilgrimage, loved fiqh and fuqaha' and loathed kalam disputation; he wept convulsively at Abu Mu'awiya al-Darir's hadith 'I would love to be killed in God's path then live again' yet was told his place in Islam was too great to go raiding in person. He died at Tus on Saturday night, four days into Jumada II 193, buried at Sanabadh with his son Salih praying over him — forty-five years old after twenty-three years, two months and sixteen days of rule.
