It is narrated from Sayyida Asma bint Umais (may Allah be pleased with her) that she delivered Muhammad bin Abi Bakr at Al-Bayda, so she mentioned this to Sayyiduna Abu Bakr (may Allah be pleased with him), who mentioned it to the Messenger of Allah (peace and blessings be upon him). He (peace be upon him) said: "Take a bath and enter into Ihram."
