On the terrace-roof of a convent perched, like a turban on a tall man's head, on the top of a steep hill, the lesser chain of the Jabal Hauran, the most learned monk, Bahira, looked out afar over the Syrian plains, stretching away in infinite space in the direction of Arabia. All of a sudden, his attention was drawn to the strange aspect of a solitary cloud, white and oblong, that stood out in bold relief on the immaculate blue background of the sky. Like some enormous bird, the cloud hovered above a small caravan winding its way northwards. The fleecy mass in the heavens covered the straggling procession with its azure shade and moved with the line of travellers. At the foot of the hill on which the monastery was built, the caravan halted, close to a great tree that grew on the brink of a dried-up wady, and began to organise the encampment. At that moment, the cloud stopped still and vanished in the celestial canopy, while the branches of the tree were bent, as if beneath the gusts of a breeze acting on those twigs and leaves, at the same time throwing their shade over one of the caravaneers, as if to protect him from the blazing rays of the sun. Seeing these prodigies, Bahira guessed that among these wayfarers coming from the Hijaz, would be found the man he had been awaiting so long: the Prophet announced by the Sacred Books. So Bahira hurried down from the flat roof, gave orders to prepare a bountiful meal and sent a messenger to invite all the folks of the caravan without exception, young or old, nobles or slaves. The messenger returned, in company with the men of Makkah whose coming Bahira awaited on the threshold of his monastery. 'By Lat and Uzza! thy conduct doth puzzle me, O Bahira!' exclaimed one of the guests. 'Many a time and oft have we passed by the convent; yet, until now thou hast never heeded us; never didst thou dream of showing us the least sign of hospitality. What maggot biteth thee this day?'--'Thou dost not err,' replied Bahira. 'I have cogent reasons for behaving as I do. But ye are my guests at this hour and I pray that ye honour me by gathering together to partake of the repast that I have prepared for you all.'
