of their passage could not be guaranteed. Al-Qadir also tried to make the emir Abu'l-Futuh abandon the Fatimids and return to Abbasid allegiance, but without success. As a further reaction, in November 1011 al-Qadir issued the Baghdad Manifesto, signed by both Sunni and Twelver scholars. The document not only condemned the Fatimid doctrine as false, but denounced their claims to descent from Ali as fraudulent, and their followers as enemies of Islam. The Baha al-Dawla died in 1012, and was succeeded by his son, Sultan al-Dawla (). The succession did nothing to halt the decline of the Buyid power in Iraq, or the mounting Sunni–Shi'a tension, but it did offer al-Qadir greater freedom of action. In 1017, he condemned Mu'tazilite and Shi'a doctrines, and ordered those jurists of the Hanafi school who had shown Mu'tazilite tendencies to do penance. Shortly after, in 1018, inspired by Hanbali ideas, he issued a decree, the ('Epistle of al-Qadir'), which for the first time explicitly formulated Sunni doctrine. The decree condemned Shi'a, Mu'tazilite, and even Ash'arite doctrines, and affirmed the veneration of the first four caliphs (the "Rashidun"), and of the Companions of Muhammad, as an obligation for all Muslims, against Shi'a beliefs that the first three caliphs had been illegitimate, as they had deprived Ali (the fourth caliph) of his rightful inheritance. Relations with the Buyids In 1021, Sultan al-Dawla ceded rule over Iraq to his younger brother, Musharrif al-Dawla (). The latter came to Baghdad in March 1023, and ordered al-Qadir to come to him. Al-Qadir complied, but when Musharrif al-Dawla went on to renew the oath of allegiance of the Turkic military officers without asking for the Caliph's permission, al-Qadir protested, and in return secured a pledge of fidelity from Musharrif al-Dawla. When the latter died in 1025, Musharrif al-Dawla's brother Jalal al-Dawla () and his nephew, Abu Kalijar, clashed over his inheritance; the latter was proclaimed as by the soldiery, and initially recognized as such by the Caliph, but he was toppled when the troops eventually defected to Jalal al-Dawla. Jalal al-Dawla entered Baghdad in 1026 and began curtailing the caliph's powers, but his rule was short-lived, as once again the troops turned against him. Al-Qadir sent a delegation to inform him that he must leave the capital, and prohibited him from returning for several years. Final years During his last years, al-Qadir reiterated and reinforced his theological doctrines. In
