What is "al-qata'i"

Al-Qaṭāʾi (Arabic: القطائـع) was the short-lived Tulunid capital of Egypt, founded by Ahmad ibn Tulun in the year 868 CE. Al-Qata'i was located immediately to the northeast of the previous capital, al-Askar, which in turn was adjacent to the settlement of Fustat. All three settlements were later incorporated into the city of al-Qahira ( Cairo), founded by the Fatimids in 969 CE. The city was razed in the early 10th century CE, and the only surviving structure is the Mosque of Ibn Tulun.
