Rabi'ah ibn Ahmad ibn Tulun

Abū al-Mukarram Rabīʿah ibn Aḥmad ibn Ṭūlūn(Arabic: ابو المكارم ربيعة بن أحمد بن طولون‎‎) was the fourth son of the founder of the Tulunid dynasty, Ahmad ibn Tulun. In 879, when his eldest brother Abbas rebelled against their father and fled to Alexandria and thence to Barqah, he remained in charge of affairs in Fustat until the return of Ahmad ibn Tulun. In 897, he rebelled against his nephew, Harun ibn Khumarawayh, in Alexandria, with the support of Berber troops. The uprising was defeated, and he was executed by lashing in the same autumn.
