How was the Prophet, may God's prayers and peace be upon him, who was given the strength of 40 men or 4,0 men, defeated by Ibn Qami'ah in the Battle of Uhud?

What befell the Prophet, may Allah bless him and grant him peace, on the Day of Uhud does not contradict his courage and strength. Rather, it was to magnify his reward, as the polytheists pelted him with stones, wounding him and embedding the rings of his helmet into his cheek.

As for his physical strength, the hadith, "I was given the strength of forty in might and intercourse," is weak. However, it is authentically reported in Sahih al-Bukhari from Anas that he, may Allah bless him and grant him peace, "was given the strength of thirty." As for the strength of four thousand, it is an inference made by some scholars based on various narrations.
