In the course of the later eleventh and twelfth century, however, the Fatimid caliphate declined rapidly, and in 1171 the country was invaded by Ṣalāḥ ad-Dīn, the founder of the Ayyubid dynasty. He restored Egypt as a political power, reincorporated it in the Abbasid caliphate and established Ayyubid suzerainty not only over Egypt and Syria but, as mentioned above, temporarily over northern Mesopotamia as well.
Rejected by the majority of Muslims as heretical since it believes in ongoing prophethood after the death of Muhammad. Currently based in Pakistan, but forbidden to practice, preach, or propagate their faith as Islam or their places of worship as mosques.
As the Arabs of the Ḥejāz had used the drahms of the Sasanian emperors, the only silver coinage in the world at that time, it was natural for them to leave many of the Sasanian mints in operation, striking coins like those of the emperors in every detail except for the addition of brief Arabic inscriptions like besmellāh in the margins. [...] In the year 79/698 reformed Islamic dirhams with inscriptions and no images replaced the Sasanian types at nearly all mints. During this transitional period in the 690s specifically Muslim inscriptions appeared on the coins for the first time; previously Allāh (God) had been mentioned but not the prophet Moḥammad, and there had been no reference to any Islamic doctrines. Owing to civil unrest (e.g., the revolt of ʿAbd-al-Raḥmān b. Ašʿaṯ, q.v., against Ḥajjāj in 81/701), coins of Sasanian type continued to be issued at certain mints in Fārs, Kermān, and Sīstān, but by 84/703 these mints had either been closed down or converted to production of the new dirhams. The latest known Arab-Sasanian coin, an extraordinary issue, is dated 85/704-05, though some mints in the east, still outside Muslim control, continued producing imitation Arab-Sasanian types for perhaps another century.
