But much as Islam may have owed to the martial prowess of such fanatics as these, there is the overwhelming testimony of travellers and others to the peaceful missionary preaching, and quiet and persistent labours of the Muslim propagandist, which have done more for the rapid spread of Islam in modern Africa than any violent measures: by the latter its opponents may indeed have been exterminated, but by the former chiefly, have its converts been made, and the work of conversion may still be observed in progress in many regions of the coast and the interior. [1166] Wherever Islam has made its way, there is the Muhammadan missionary to be found bearing witness to its doctrines,—the trader, be he Arab, Pul or Mandingo, who combines proselytism with the sale of his merchandise, and whose very profession brings him into close and immediate contact with those he would convert, and disarms any possible suspicion of sinister motives; such a man when he enters a pagan village soon attracts attention by his frequent ablutions and regularly recurring times of prayer and prostration, in which he appears to be conversing with some invisible being, and by his very assumption of intellectual and moral superiority, commands the respect and confidence of the heathen people, to whom at the same time he shows himself ready and willing to communicate his high privileges and knowledge;—the ḥājī or pilgrim who has returned from Mecca full of enthusiasm for the spread of the faith, to which he devotes his whole energies, wandering about from place to place, supported by the alms of the faithful who bear witness to the truth in the midst of their pagan neighbours;—the student who, in consequence of his knowledge of Islamic theology and law, receives honour as a man of learning: sometimes, too, he practises medicine, or at least he is in great requisition as a writer of charms, texts from the Qurʼān, which are sewn up in pieces of leather or cloth and tied on the arms, or round the neck, and which he can turn to account as a means of adding to the number of his converts: for instance, when childless women or those who have lost their children in infancy, apply for these charms, as a condition of success the obligation is always imposed upon them of bringing up their future children as Muhammadans. [1167] These religious teachers, or marabouts, or alūfas as they are variously termed, are held in the highest estimation. In some tribes of Western Africa every village contains a lodge for their reception, and they are treated with the utmost deference and respect: in Darfur they hold the highest rank after those who fill the offices of government: among the Mandingos they rank still higher, and receive honour next to the king, the subordinate chiefs being regarded as their inferiors in point of dignity: in those states in which the Qurʼān is made the rule of government in all civil matters, their services are in great demand, in order to interpret its meaning.
