Death of Abū Bakr al-Ṣiddīq

Abū Bakr died on a Monday night, 22 Jumādā al-Ākhirah 13 AH, aged sixty-three — the same age as the Prophet ﷺ, as the sources note — after a fever of fifteen days.

His caliphate lasted two years and three months and decided more than most reigns ten times longer: the community held together at Saqīfah, the riddah wars kept Arabia from dissolving, the armies entered Iraq and Syria, and the Qurʾān was gathered into a single collection. Dying, he named ʿUmar — a written designation that spared the community a second succession crisis.

He was buried beside the Prophet ﷺ in ʿĀʾishah's chamber. The date is carried consistently in the Madinan tradition.
