Ja’far bin Muhammad said: “My father told me: ‘We came to Jabir bin ‘Abdullah and asked him about the Hajj of the Prophet صلی اللہ علیہ وآلہ وسلم. He narrated: ‘The Messenger of Allah صلی اللہ علیہ وآلہ وسلم set out when there were five (days) remaining in Dhul Qa’dah, and we set out with him. When he came to Dhul-Hulaifah, Asma’ bint ‘Umais gave birth to Muhammad bin Abi Bakr. She sent word to the Messenger of Allah صلی اللہ علیہ وآلہ وسلم asking what she should do. He said: ‘Perform Ghusl, bind yourself with a cloth then begin (the Talbiyah for Ihram).''' (Sahih)
