“Our Prophet (peace be upon him) suffered much abuse and torture at the hands of the polytheists.”
This never happened. Unlike some of his less fortunate followers, Muhammad enjoyed the protection of his powerful uncle, Abu Talib:
But Abu Talib would not relent:
For thirteen years, the worst that ever happened to Muhammad at Mecca was that he had dust thrown on him by a heckler and was occasionally mocked while praying at the Kaaba. He continued to provoke the Meccans, at one point telling them that he had come to bring them “slaughter” (Tabari Vol. IV, page 101) This caused them to seize Muhammad in an attempt (by one named Uqba) to “throttle” him, but he was released unharmed almost immediately:
Muhammad would have his opportunity to forgive the man who had seized him when Uqba was captured following the Battle of Badr. According to his biographers, the prophet of Islam chose instead to have him slaughtered even as the unarmed prisoner begged for his life.
The Hadith also confirms that Muhammad was not physically harmed by the Meccans:
As mentioned in several places, the worst indignity that Muhammad endured was an episode in which Abu Jahl and others mocked him while he was praying by putting the intestines of an animal on his back (Bukhari 4:241). The men who did this were later killed by the Muslims.
Neither does the Quran provide any support for the contemporary thesis that Muhammad suffered physical abuse at Mecca, despite the many harsh things said about those who rejected him – the redundancy of which is so abundant in the Quran that it comprises the majority of the text.
There is also an entire Sura is devoted to describing the gruesome and sadistic torture awaiting Abu Lahab and his wife in hell, who are the only people mentioned by name in the Quran (other than Muhammad and his son-in-law Zaid). Yet, according to the authentic Hadith, their only crime was personal mockery of “the Messenger” at Mecca (Muslim 406, Bukhari 60:475).
