Moved by their despair, the Prophet made an urgent appeal to the devotion of all the Believers who, with admirable emulation, replied at once by bringing considerable sums. Abu Bakr placed the whole of his fortune at the disposition of the Prophet. Usman ibn Affan furnished ten thousand warriors with provisions and weapons. All vied with each other in acts of generosity and women stripped themselves of their most precious jewellery. The expeditionary force was soon organised and numbered between thirty to forty thousand men; a figure hitherto unknown in Arabia. The troops were assembled at the Sanniyat-ul-Wida pass. Seeing the exaltation of the Believers, the "Hypocrites" considered it prudent to conceal their sentiments, but they arranged to group themselves together in the rear and when the army had disappeared behind the "Farewell Pass," the shufflers dropped out, one after the other, and made their way back to Al-Madinah. Their conduct was not surprising, but unfortunately their fatal advice had deterred four good Moslems from their duty: the poet Ka'b ibn Mabk, Murara ibnu'r-Rabi', Hilal ibn Umayya and Abu Khaythama. The latter, suffocated by the extreme heat and also, perchance, by feelings of shame, went into his orchard, surrounded by protecting walls. It was there, under intertwining palms and vine-branches with leaves and grapes, which stretched like serpentine bind-weeds from one date-tree to another, that two shelters were erected, built of palm-tree trunks and foliage; so impervious to sunlight that the obscurity therein seemed to be the shades of night. To complete the resemblance, the mysterious darkness of each of these arbours was illuminated by a young woman's face, as brilliant as the moon in the fulness of its fourteenth night. Kindly attentive as well as beautiful, these loving spouses had carefully watered the sandy soil, whence arose exquisite, moist odours. Ingeniously, too, they had hung up, in draughty corners, oozing goat-skins in which water got to be as cool as snow; and they had prepared delicate dishes of which the aroma sufficed to excite the most rebellious appetite.... Abu Khaythama, bathed in sweat, powdered all over with sand, experienced a sensation of Eden-like comfort, when he glanced at the delights in readiness and was about to revel in enjoyment by lazily stretching his limbs on soft rugs. But, suddenly, the emerald-tinted reflection of the shade that gently caressed his tired eyes, was furrowed by the flash of a vision: In a gloomy, wild, boundless space, beneath the deep azure hue of a cloudless sky, under the unbearable sting of a pitiless sun, a long line of human beings dragged itself along with difficulty, coming into view and then being lost to sight amid yellowish waves formed by rocks or sandheaps.... He recognised these mortals. They were his brethren in Islam. At their head was ... Allah's Chosen One!
