فتح مكة
According to an observation in al-Qastallani's "Al-Muwahib al-Ladunniyyah", an untold number of persons had already converted to Islam by the time Muhammad died. There were 10,000 by the time of the Conquest of Mecca and 70,000 during the Expedition of Tabuk in 630. Some Muslims assert that they were more than 200,000 in number: it is believed that 124,000 witnessed the Farewell Sermon Muhammad delivered after making Farewell Pilgrimage to Mecca.
