In 605 AH: a mighty earthquake struck Nishapur; it lasted for ten days, and multitudes perished beneath the debris.
In 606 AH: the Georgian king laid siege to Khilat and nearly captured it. Inside the town was al-Awhad, son of al-Malik al-ʿĀdil. His court astrologer, Iioay (1), told him, “You will spend this very night in the citadel of Khilat.” As it happened, the astrologer became intoxicated, led an assault with his troops, the Muslims sallied out, battle was joined, many were slain, and Iioay was taken prisoner—so he did indeed spend the night in the citadel. The Georgians next invested Arjish (2) and captured it by the sword.
Al-ʿĀdil at times neglected jihad and fought purely for worldly gain; he besieged Sinjar for a while.
Ibn al-Athir (3) reports: Khwarazm-Shah advanced, crossed the Jayhun River with his armies, and was confronted by Tayanku, the despot of the Khitans. The Khitans were routed, their king was taken prisoner, and Khwarazm-Shah sent him on to Khwarazm. The ruler of Samarqand rebelled against his father-in-law (4) Khwarazm-Shah, acted tyrannically, mutinied, and killed the Khwarazmian troops stationed with him. Khwarazm-Shah marched against him, seized Samarqand, and put the city to the sword—it is said that two hundred thousand Muslims were killed there. He then turned on the fortress, captured its ruler, and slaughtered him.
(5) About this time the first rumors of the Tatars were heard. They emerged from their lands in the deserts of China beyond Turkistan, fought the Khitans repeatedly, and their strength grew after the Khitans’ defeat at the hands of Khwarazm-Shah
