The Quran is, then, believed to be a miraculous revelation of divine eloquence, as regards both _form_ and _substance_, arrangement of words, and its revelation of sacred things. It is asserted that each well-accredited prophet performed miracles in that particular department of human skill or science most flourishing in his age. Thus in the days of Moses magic exercised a wide influence, but all the magicians of Pharaoh's court had to submit to the superior skill of the Hebrew prophet. In the days of Jesus the science of medicine flourished. Men possessed great skill in the art of healing; but no physician could equal the skill of Jesus, who not only healed the sick, but raised the dead. In the days of Muhammad the special and most striking feature of the age was the wonderful power of the Arabs in the art of poetry. Muhammad-ud-Damiri says:--"Wisdom hath alighted on three things--the brain of the Franks, the hands of the Chinese and the tongue of the Arabs." They were unrivalled for their eloquence, for the skill with which they arranged their material and gave expression to their thoughts. It is in this very particular that superior excellence is claimed for the Quran.[6] It is to the Muhammadan mind a sure evidence of its miraculous origin that it should excel in this respect. Muslims say that miracles have followed the revelations given to other prophets in order to confirm the divine message. In this case the Quran is both a revelation and a miracle. {6} Muhammad himself said:--"Each prophet has received manifest signs which carried conviction to men: but that which I have received is the revelation. So I hope to have a larger following on the day of resurrection than any other prophet has." Ibn Khaldoun says that "by this the Prophet means that such a wonderful miracle as the Quran, which is also a revelation, should carry conviction to a very large number."[7] To a Muslim the fact is quite clear, and so to him the Quran is far superior to all the preceding books. Muhammad is said to have convinced a rival, Lebid, a poet-laureate, of the truth of his mission by reciting to him a portion of the now second Sura. "Unquestionably it is one of the very grandest specimens of Koranic or Arabic diction.... But even descriptions of this kind, grand as they be, are not sufficient to kindle and preserve the enthusiasm and the faith and the hope of a nation like the Arabs.... The poets before him had sung of valour and generosity, of love and strife and revenge ... of early graves, upon which weeps the morning cloud, and of the fleeting nature of life which comes and goes as the waves of the desert sands, as the tents of a caravan, as a flower that shoots up and dies away. Or they shoot their bitter arrows of satire right into the enemy's own soul. Muhammad sang of none of these. No love-minstrelsy his, not the joys of the world, nor sword, nor camel, nor jealousy, nor human vengeance, not the glories of tribe or ancestor.
