It was narrated from Abu Bakr that he went out for Hajj with the Messenger of Allah صلی اللہ علیہ وآلہ وسلم on the Farewell Pilgrimage, and his wife Asma’ bint ‘Umais Al-Khath’amiyyah was with him. When they were at Dhul-Hulaifah, Asma’ gave birth to Muhammad bin Abi Bakr. Abu Bakr came to the Prophet and told him, and the Messenger of Allah صلی اللہ علیہ وآلہ وسلم told him to tell her to perform Ghusl, then begin the Talbiyah for Hajj, and to do everything that the people do, except that she should not circumambulate the House. (Sahih)
