With the death of the Negus—may Allah be pleased with him—the authority that had protected both the call and those engaged in it had disappeared.
When Islam had extended its dominion over most of the world and the Arabs had entered Allah’s religion in multitudes—specifically, early in the reign of the third caliph, ‘Uthmān ibn ‘Affān, may Allah be pleased with him—the Islamic call began to spread across the continent once more.
