War-Dyābe, also known as War-Ndyay, is identified as the first Muslim king of Takrur. His reign belongs to the formative phase of Takrur’s Islamization, which the passage places in the pre-Almoravid period. His political role connected the lower Senegal kingdom to the wider religious transformations that preceded Almoravid expansion.

War-Dyābe died in 1040/1, around the time Ibn Yāsīn first came to the desert. The timing is significant because the Almoravid movement was then taking shape among Saharan groups, while Takrur had already begun adopting Islam. War-Dyābe’s death thus falls at the intersection of Takrur’s early Muslim kingship and the emergence of Almoravid power.

His son Labi later joined Yahyā ibn ʿUmar in fighting the rebellious Judāla in 1056. Through this succession and alliance, War-Dyābe’s family became connected to the political and military cooperation between Takrur and the Almoravids.

War-Dyābe ibn Rābīs appears in an account of Takrūr on the Lower Senegal as the ruler under whom the kingdom adopted Islam. The population is described as having previously worshipped idols called dakākīr in their language. His significance lies in the political and legal dimensions attributed to his conversion, rather than in a detailed biography preserved on these pages.

The account credits War-Dyābe with adopting Islam and introducing Islamic law. He is said to have compelled the people to observe its rules and to have opened their eyes to what the passage calls the Truth. This portrayal contrasts sharply with the more nominal and partial acceptance of Islam described for Gao.

The pages provide no precise date for War-Dyābe’s reign and do not establish the extent to which the reported transformation immediately affected all inhabitants of Takrūr. His place in the narrative is that of a ruler whose authority was used to associate Islamic belief and law with the political order of the Lower Senegal kingdom.
