sent thirty thousand men with his son al-Mahdi to Rayy, forty thousand with Muhammad ibn al-Ashʿath to Ifriqiyah, and left the rest with ʿIsa ibn Musa in the Hijaz; only two thousand cavalry remained with al-Mansur himself. At night he would order many watch-fires to be lit so that anyone looking on would imagine a large army was camped there.
Al-Mansur then wrote to ʿIsa ibn Musa: “The moment you read this letter, come to me immediately and leave whatever you are occupied with.” Scarcely had the letter reached him before he set out. When he arrived, al-Mansur said to him:
“Go to Ibrahim in Basra. Let not the size of the host with him alarm you, for they are merely the two slaughtered camels of the Banu Hashim. Stretch forth your hand, trust in the forces you command, and you will recall my words.” Events unfolded exactly as al-Mansur had predicted.
Al-Mansur also wrote to his son al-Mahdi, instructing him to dispatch Khazim ibn Khuzaymah with four thousand men to Ahwaz. Khazim marched there, expelled Ibrahim’s deputy—al-Mughirah—allowed the city to be plundered for three days, and al-Mughirah retreated to Basra. In the same way al-Mansur sent detachments to every district that had broken its pledge, forcing the inhabitants back into obedience.
They relate that al-Mansur stayed constantly at the spot where he performed his prayers, never leaving it night or day, clad in shabby garments that had become soiled. He remained there for a little over fifty days until Allah granted him victory. During that period someone said to him (1): “Your wives have grown discontented because of your prolonged absence from them.” He rebuked the speaker, saying, “Woe to you! These are no days for women until I see Ibrahim’s head before me—or my own head is carried to him.”
One observer recounts: “I came in to al-Mansur while he was weighed down by the many evils that had befallen him; so great was his anguish and worry that he could scarcely complete a sentence. Yet for every breach or tear he had already prepared something to mend it. Basra, Ahwaz, Fars, al-Madaʾin, and the Sawad had slipped from his grasp, and in Kufah there were one hundred thousand men with sheathed swords awaiting but a single cry to rise with Ibrahim. Even so, he grappled with each calamity and subdued it; his spirit never failed him.
He was, as the poet said:
‘The soul of ʿIsam ennobled ʿIsam,
teaching him to charge and to advance;
It fashioned him into a gallant king.’ (2)
Ibrahim advanced from Basra toward Kufah with an army of one hundred thousand fighting men. Al-Mansur sent ʿIsa ibn Musa against him with fifteen thousand, the vanguard being Humayd ibn Qahtabah with three thousand. Ibrahim arrived and encamped at Bakhumra (3) with vast hosts. Some of his commanders said to him, “You are now close to al-Mansur; if you were to march against him with a detachment of your troops you would seize him from the rear, for he has not the forces to repel you.”
Others said: “The better course is to…"
