they will be clothed in the richest silks, chiefly of green. They are also promised perpetual youth, and children as many as they may desire. These pleasures, together with the songs of the angel Isráfeel, and many other gratifications of the senses, will charm even the meanest inhabitant of Paradise. But all these enjoyments will be lightly esteemed by those more blessed persons who are to be admitted to the highest of all honours—that spiritual pleasure of beholding, morning and evening, the face of God.[106]—The Muslim must also believe in the examination of the dead in the sepulchre, by two angels, called Munkar and Nekeer, of terrible aspect, who will cause the body (to which the soul shall, for the time, be re-united) to sit upright in the grave,[107] and will question the deceased respecting his faith. The wicked they will severely torture; but the good they will not hurt. Lastly, he should believe in God’s absolute decree of every event, both good and evil. This doctrine has given rise to as much controversy among the Muslims as among Christians; but the former, generally, believe in predestination as, in some respects, conditional. The most important duties enjoined in the _ritual and moral laws_ are _prayer, alms-giving, fasting_, and _pilgrimage_. The religious _purifications_, which are of two kinds,—first, the ordinary ablution preparatory to _prayer_, and secondly, the washing of the whole body, together with the performance of the former ablution,—are of primary importance: for prayer, which is a duty so important that it is called “the Key of Paradise,” will not be accepted from a person in a state of uncleanness. It is therefore also necessary to avoid impurity by clipping the nails, and other similar practices.[108]
