After a hot day followed a very fine evening, with a beautifully-clear moonlight; and cherishing the fervent hope that, with the assistance of the Almighty, I should succeed in my dangerous undertaking, I lay down in the open encampment, and listened with hearty sympathy to the fervent prayers of the Tinýlkum, which in melodious cadence, and accompanied with the sound há, há, sometimes in a voice of thunder, at others in a melancholy unearthly plaint, were well adapted to make a deep impression upon the mind, the tall palm-trees forming majestic groups, and giving a fanciful character to the landscape in the calm moonlight. It is a remarkable fact that, while the Mohammedan religion in general is manifestly sinking to corruption along the coast, there are ascetic sects rising up in the interior which unite its last zealous followers by a religious band. The particular sect to which belong the Tinýlkum, who in general are Máleki, has been founded by Mohammed el Médani, who established a sort of convent or oratory (zawíya) near Masráta, and endowed it with a certain extent of landed property, from the produce of which he fed many pilgrims. The best feature of this creed is the abolition of the veneration of dead saints, which has sullied in so high a degree the purity of Islám. Mohammed el Médani is said to have died a short time ago; but his son continues the pious establishment.[58] It is a sort of freemasonry, and promises to make a great many proselytes. I am not one of those who think it a sign of progress when Mohammedans become indifferent to the precepts of their religion, and learn to indulge in drinking and such things; for I have not given up my belief that there is a vital principle in Islám, which has only to be brought out by a reformer, in order to accomplish great things. In Tasáwa also reside a few Tinýlkum, who, however, have been intimately intermixed with the Arabs, while the others in general keep their blood pure, and do not intermarry with the people of Fezzán.
