Leroux, pp. 131 : "The Almoravids always had black standards and we know that black was also the color of the first Abbasids. We do not think that we can see in the adoption of this color by the Almoravids a means of marking their attachment to the Abbasid caliphate... We think that into the black color of the Almoravid standards, we must see a symbol, the interpretation of which Mr. Van Vioten very clearly explained: The black color of the standards marks the fight against impiety and error, he says, according to the poet El-Komaït; in addition, the black flags represent the flag of the Prophet, to which all our sources agree to attribute the color black. Cf. Research on Arab Domination, Chitism and Messianic Beliefs under the Umayyad Caliphate, Amsterdam, 1894, p. 64. This is enough to show us how, from the start, the Almoravids were able to adopt the black flag, to clearly mark the religious character of their invasion."

This is an obvious thing if we know that the Almoravids adopted all the symbols of the Abbasids, including the color. Al-Aswad, on the other hand, confirms that the Almoravids’ connection with the Abbasids began from the very beginning of their movement, which reinforces the idea of the fluidity of the Sunni tide in the Islamic world, east and west."
