'Amr bin Dinar narrated with the same chain of transmitters that he heard the Messenger of Allah (ﷺ) delivering sermon at 'Arafat, and he made a mention of this hadith (as quoted above).
Jabir bin'Abdullah (RA) reported that when Asma' bint Umais gave birth (to a child) in Dhu'I-Hulaifa. Allah's Messenger (ﷺ) commanded Abu Bakr (RA) (to convey to her) that she should take a bath and enter into the state of Ihram.
Anas bin Malik (RA) reported that Allah's Messenger (ﷺ) died when he was sixty-three years old, and so was the case with Abu Bakr, and so was the case with Umar who was also sixty-three (when he died).
