Evidence that the Prophet waited for Aisha to reach physical maturity before consummation comes from al-Ṭabarī, who says she was too young for intercourse at the time of the marriage contract;
{{cite book}}: ISBN / Date incompatibility (help)Criticism by Christians [...] was voiced soon after the advent of Islam starting with St. John of Damascus in the late seventh century, who wrote of "the false prophet", Muhammad. Rivalry, and often enmity, continued between the European Christian world and the Islamic world [...]. For Christian theologians, the "Other" was the infidel, the Muslim. [...] Theological disputes in Baghdad and Damascus, in the eighth to the tenth century, and in Andalusia up to the fourteenth century led Christian Orthodox and Byzantine theologians and rulers to continue seeing Islam as a threat. In the twelfth century, Peter the Venerable [...] who had the Koran translated into Latin, regarded Islam as a Christian heresy and Muhammad as a sexually self-indulgent and a murderer. [...] However, he called for the conversion, not the extermination, of Muslims. A century later, St. Thomas Aquinas in Summa contra Gentiles accused Muhammad of seducing people by promises of carnal pleasure, uttering truths mingled with many fables and announcing utterly false decisions that had no divine inspiration. Those who followed Muhammad were regarded by Aquinas as brutal, ignorant "beast-like men" and desert wanderers. Through them Muhammad, who asserted he was "sent in the power of arms", forced others to become followers by violence and armed power.

{{citation}}: ISBN / Date incompatibility (help)The Jews [...] could not let pass unchallenged the way in which the Koran appropriated Biblical accounts and personages; for instance, its making Abraham an Arab and the founder of the Ka'bah at Mecca. The prophet, who looked upon every evident correction of his gospel as an attack upon his own reputation, brooked no contradiction, and unhesitatingly threw down the gauntlet to the Jews. Numerous passages in the Koran show how he gradually went from slight thrusts to malicious vituperations and brutal attacks on the customs and beliefs of the Jews. When they justified themselves by referring to the Bible, Muhammad, who had taken nothing therefrom at first hand, accused them of intentionally concealing its true meaning or of entirely misunderstanding it, and taunted them with being "asses who carry books" (sura lxii. 5). The increasing bitterness of this vituperation, which was similarly directed against the less numerous Christians of Medina, indicated that in time Muhammad would not hesitate to proceed to actual hostilities. The outbreak of the latter was deferred by the fact that the hatred of the prophet was turned more forcibly in another direction, namely, against the people of Mecca, whose earlier refusal of Islam and whose attitude toward the community appeared to him at Medina as a personal insult which constituted a sufficient cause for war.

As Voltaire's knowledge of Islam deepened, he clearly became better disposed towards the faith.
As was customary for Arab chiefs, many were political marriages to cement alliances. Others were marriages to the widows of his companions who had fallen in combat and were in need of protection. Remarriage was difficult in a society that emphasized virgin marriages. Aisha was the only virgin that Muhammad married and the wife with whom he had the closest relationship. Fifth, as we shall see later, Muhammad's teachings and actions, as well as the Quranic message, improved the status of all women—wives, daughters, mothers, widows, and orphans.
