The Age of Aisha, the Mother of the Believers (RA)

Al-Rabii said: "Abu Obeida reported from Jabir ibn Zaid that Aisha (may Allah be pleased with her) was married to the Messenger of Allah (Allah's peace and prayers be upon him) when she was six years old; and he consummated his marriage with her when she was nine years old.  He did not marry a virgin among his wives except her. And when he died she was eighteen years old. She lived after him for forty eight years. She died during the time of Mu'awiyah; that is Ramadhan, year fifty eight.  Abu Hurairah offered funeral prayer for her, and she was buried in al-Baqi. The number of her Hadiths is sixty eight."
