In 1887, Rabih's forces invaded Darfur, recruited "bazingirs", and settled down in Dar Kouti; however, his campaign against the "aguid" Salamat Cherif ed-Din, commander of the sultan of Ouaddai's troops, failed. In 1890, he attacked the Muslim chief Kobur in the north of Oubangui-Chari, deposed him and established in his place his nephew Mahdi al-Senoussi, on whom he imposed his suzerainty. This alliance was sealed by the marriage of Khadija, daughter of Al-Mahdi al-Senoussi, with Rabih's son Fadlallah. Together Mohammed and Rabih attacked Dar Runga, Kreich, Goula and then Banda Ngao.
