All who assisted at this scene were shaken by sobs. All of a sudden, their faces took on a livid tint, which, at the same time, spread over the earth, the sand, and the rocks. The azure of the sky changed to a leaden hue; the sunlight paled and gradually faded away, although no clouds gathered to veil it. An icy shudder, resembling that of fever, caused the whole face of nature to be stirred; and the birds, with cries of fright, took refuge in their nocturnal shelters. The last rays, still illuminating surrounding objects with dim and sinister light, began to die away and darkness came on in open day, whilst a few twinkling stars appeared in the sky. The people in terror knew not which way to turn so as to escape the fearful cataclysm they anticipated. Many in the crowd, struck by the phenomenon coinciding with the death of Ibrahim, cried out: 'O Prophet! the eyes of the sun itself are dimmed by tears and it hath departed to take part in thy mourning!' The Prophet, struggling against his grief, drew himself up erect and proclaimed in firm accents: 'Nay; it is not so. The Sun and the Moon are two tokens of Allah's Almightiness. Like everything beautiful in this world, their beauty is liable to be eclipsed by His orders.... But there is no eclipse for the death of any mortal!' [Sidenote: GHAZWAH, OR EXPEDITION OF TABUK (_Jumada, Year VIII of the Hegira, August A.D. 630_)] At the battle of Mutah, the Christian Greeks learnt to their cost what it meant to put the valour of Allah's warriors to the test; and in their hatred of Islam's steady growth, they busied themselves in mustering a most terrible army to crush it. The Prophet heard of this. He resolved to be first in the field and attack. Only his unshaken confidence in divine protection could have inspired him with such temerity. How many thousands of soldiers must he gather together so as not to court irretrievable disaster? Now the moment was not in the least favourable: a long drought had withered crops and herbage; flocks were decimated; horrible famine plunged the whole region in desolation; and the torrid heat of the second half of summer destroyed all energy. The harvest of the savoury fruit of each oasis, watered by inexhaustible wells, alone promised to be abundant and invigorating; and it was precisely when the Faithful were about to profit by the only benefits of this lean year that the Apostle issued his marching orders. Secret discontent invaded every heart and the incorrigible "Hypocrites" hastened to exploit it by hawking about everywhere perfidious remarks, such as these: 'Do ye think this war against the Banu'l-Asfar (the descendants of fair-headed Ishaq) will be child's play, as was that against the swarthy sons of Ishmael? Remember that arriving exhausted by the intolerable heat of the season and the superhuman fatigue of the road, ye will have to face the Nazarene soldiers encased in armour!'
