Medieval Christian polemicists attacked the Prophet’s biography as the strongest disproof of Islam.

Evidence

THE life of Muhammad was seen as an essential disproof of the Islamic claim to Revelation. It was often treated as the most important disproof of all. To this end writers believed and wished to show that Muhammad was a low-born and pagan upstart, who schemed himself into power, who maintained it by pretended revelations, and who spread it both by violence and by permitting to others the same lascivious practices as he indulged in himself. — Norman Daniel, Islam and the West, 449
