Leaving the "arish" abruptly, he called out to his army: 'Our enemies are routed! Already I see their backs turned in wild flight! I swear by Him who holdeth Mohammad's soul in the hollow of His hand, that any Believer killing a foe hath the right to his spoils; and any Believer killed face to the enemy will be immediately welcomed by Allah in the gardens of Paradise.'

Amir ibn Hammam, listening to these promises, held a handful of dates, and was about to lift them to his mouth, when he threw them on the ground with a sudden gesture of disdain, and shouted in tones of joyous exaltation: 'Bakhr! Bakhr! Considering that between me and my entry into Paradise there is only the slight barrier of death at the hands of the men over there'. Without finishing the sentence, he drew his sword and fell on the idolaters, digging a bloody road through their ranks, until be succumbed outnumbered.

Another among the Faithful having heard the Prophet declare that Allah would consider the martyr fighting with no armour than that of his faith to be more deserving than any, threw off his breastplate and followed Amir's footsteps until he, too, fell cut to pieces, but not until he had sent many Unbelievers to the infernal regions.

From that moment, it was impossible to restrain the Believers. The Apostle scraped up a handful of dust, throwing it in the direction of the Quraish. 'May their faces be covered with confusion!' he cried. 'Forward! O Believers! Forward!'

The Faithful, like a human hurricane, threw themselves on the Unbelievers and frightful noises rent the air. The clashing of weapons, cries of despair and triumph, reverberating again and again by reason of the echoes of the valley, were accompanied by a strange uproar, sounding jerkily, like the beating a of a drum.

Quoth an Arab idolater of the Banu Ghifar: "I went with one of my cousins to the top of a hill overlooking the battlefield, so as to find out which side was victorious, meaning to join the conquerors and plunder the vanquished.

"All of a sudden, at the very moment when the warriors of Islam attacked, I saw rising up behind them, from the depths of the valley, a great pillar of sand approaching with marvellous velocity. In its tawny spirals that threatened the clouds, fantastic and terrifying visions appeared and faded. It was like a gigantic combat of the Earth rebelling against the Heavens!

"Sounds quite as strange escaped from the whirlwind, freezing my blood with horror. There was the neighing and trampling of galloping steeds; the beating of great wings; the roll of loud drums and, dominating the tumult, an imperious voice shouting: 'Forward, Haizum!'

"In less than the twinkling of an eye, the whirlwind overtook the Believers, falling with them on to the ranks of the idol-worshippers. It soon reached us as well, smothering us in its yellow darkness. I lost sight of my companion, and was nigh fainting with fear. Powerful gusts of wind drove me hither and thither, and I had to cling to projecting rocks so as not to be swept away like a wisp of straw. My ears were deafened by atrocious clamours. The curses and the groans of the wounded; the blasphemy of the vanquished, mingled now with the rumbling of thunder. In the yellow, foggy obscurity, flashes of lightning gleamed; swords and spears glittered.

"At last, when the whirlwind passed away, I saw my comrade prone on the ground, his breast torn open, showing the membrane of his heart and, like trees uprooted by a hurricane, countless dead bodies strewed the bed of the Wadi; and in the distance, lit up by a ray of sunlight, the soldiers of Islam pursued the enemy in flight."
