What is the evidence for the recommendation of the ritual bath for the one in the state of ihram?

Question:
Is there any established evidence regarding the ritual bath other than the command for the menstruating woman and the woman with post-natal bleeding?

Answer:
The hadith: "Strip yourself for your talbiyah and take a ritual bath," the hadith of Zayd, and the hadith of Ibn 'Umar: "It is a recommended practice to take a ritual bath." There is also a hadith that the menstruating woman and the woman with post-natal bleeding took a ritual bath, and a hadith of Jabir that Asma' bint 'Umayyad gave birth to Muhammad ibn Abi Bakr at Dhul-Hulayfah, so the Prophet (peace and blessings be upon him) ordered her to take a ritual bath. Likewise, 'A'ishah was ordered to take a ritual bath. If the menstruating woman and the woman with post-natal bleeding take a ritual bath, and neither has a prayer obligation upon them nor a state of ritual purity for them, then it is all the more so for others.
