Kufa
Kufa, on the Euphrates in central Iraq near Najaf, was a garrison-town (misr) founded by the Muslims around 638 during the conquest of Iraq. It became a major centre of early Arabic grammar, jurisprudence, and Shi'i scholarship, and for a time the capital of the caliph Ali; the traditionist Ibn Abi Shayba (d. 849) and the Twelver scholar Ibn Babawayh al-Saduq (d. 991) are among those connected to it.
