Ḥasan b. Abī Jāfir. He was the master of Hurmuz. He was born in the year 350 AH. His father was one of the chamberlains of ʿAdūd al-Dawla. Bahāʾ al-Dawla appointed him as vizier in the year 392 AH.
At that time, turmoil was boiling everywhere. Amidü'l-Cüyūsh brought tranquility to the country and established order. He frightened thieves, pickpockets, and marauders. Affairs got on track. One day, he ordered one of his slaves to fill a tray with dirhams, cover it, and carry it through all the streets from one end of Baghdad to the other. He instructed that if anyone tried to attack him, he should give that person the tray and the dirhams, but only mark the place. The slave filled the tray with dirhams and walked through Baghdad from end to end. No one attacked him. Vizier Amidü'l-Cüyūsh rejoiced at this situation and praised Allah.
Vizier Amidü'l-Cüyūsh forbade the Rafizī (a pejorative term for certain Shīʿī groups) from mourning on the day of ʿĀshūrāʾ, and also prohibited festivities on the eighteenth day of Dhū al-Ḥijja, known as the Ghadīr Khumm festival. He was a just and equitable person.
