Volume 1, Book 5, Number 268:
Anas bin Malik said, "The Prophet used to visit all his wives in a round, during the day and night and they were eleven in number." I asked Anas, "Had the Prophet the strength for it?" Anas replied, "We used to say that the Prophet was given the strength of thirty (men)."
I suppose that from a purely physical viewpoint, satisfying eleven women in one day is impressive. But it doesn't strike me as something a "man of God" would do.
Let's take a look at another hadith:
Volume 1, Book 6, Number 300:
When ever Allah's Apostle wanted to fondle any of his wives during the periods (menses), he used to ask her to wear an Izar.
So even though Mohammed had 11 wives, he still sometimes fondled his wives while they were menstruating. Again, this seems to show a serious lack of self-restraint. Why do you personally believe Mohammed, God's last, true prophet, a man we could say is on "the most important mission of all time", spent entire days having sex with his wives and fondling his wives while they were menstruating?
Dr. Naik: (No idea how he might respond to this one. Could be effective, especially given the fact that sex does sell).
