أمير المؤمنين
Al-Hadi was succeeded by his younger brother, Harun al-Rashid. Upon his accession, Harun led Friday prayers in Baghdad's Great Mosque and then sat publicly as officials and the layman alike lined up to swear allegiance and declare their happiness at his ascent to "Amir al-Mu'minin". He began his reign by appointing very able ministers, who carried on the work of the government so well that they greatly improved the condition of the people.
