Transoxiana, that is, the area between the Syr Darya and Amu Darya rivers. After capturing Samarkand from Babur, Shaybani married Babur's sister, Khanzada Begum. Babur's liberty to leave Samarkand was made contingent upon his assent to this alliance. After Shaybani's death, Ismail I gave liberty to Khanzada Begum with her son and, at Babur's request, sent them to his court. For this reason Shaybani was succeeded not by a son but by an uncle, a cousin and a brother whose descendants would rule Bukhara until 1598 and Khwarizm (later named Khiva) until 1687. The accounts of Babur, i.e. the Baburnama, state that the Shah of Persia Ismail beheaded Shaybani and had his skull turned into a bejeweled drinking goblet which was drunk from when entertaining; he later sent the cup to Babur as a goodwill gesture. The rest of Shaybani's body parts were either sent to various areas of the empire for display or put on a spike at the main gate of Samarkand. Personality Shaybani Khan was fond of history in his youth. In 1475, he was specially presented with a book about the life of Alexander the Great — Iskandarnamah, written in the distant Ottoman Empire. Medieval author Nisari recognized Shaybani Khan as a scholar of the Quran. The manuscript of his philosophical and religious work "Bahru’l-huda", written in the Central Asian Turkic literary language in 1508, is in London. Shaybani Khan used various works on theology when writing his essay. It contains his own views on religious issues. The author presents his own idea of the basics of Islam: repentance for sins, showing mercy, and others. Shaybani Khan shows excellent knowledge of Muslim rituals and daily duties of devout Muslims.
