This article is all about Muhammad’s youngest wife, Aisha bint Abu Bakr. After Khadija, she was Muhammad’s most beloved wife and one of the most politically important. After he died, she was a close advisor of Khalifa Umar. She led an army against ‘Ali for not prosecuting Uthman’s murderers, but was defeated. ‘Ali sent her back to Mecca to live out the rest of her life, showing his respect for her. She was considered a leading expert on the Qur’an and spoke many of the Hadiths, being one of four people who spoke over 2,000. Aishah was important to early Islam outside of being Muhammad’s wife as a religious and political leader.
