All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
Faatimah Az-Zahraa' the daughter of the Prophet was the best of all women of the world. She passed away in Al-Madeenah, six months after the death of the Prophet ; she was the first member of his family to die after him. She was buried in Al-Baqeeʻ cemetery. Ibn Saʻd wrote, "She died on a Tuesday night, on the 3rd of Ramadan, 11 AH, at the age of twenty-nine or so..." [Tabaqaat Ibn Saʻd]
It was also said that she died at the age of twenty-four or twenty-five.
Allaah knows best.
