What is the meaning of "hammam" and "kanif"? Were the hammams during the time of the Prophet, peace and blessings be upon him, like our hammams today? Where did men and women relieve themselves, bathe, and perform ablution? And did they have shampoo?

The "kanīf" is a place for relieving oneself, also called "madhhab (definition)," "mirfaq," or "mirḥāḍ." It appears that the people of Medina, before the arrival of the Messenger of Allah, peace and blessings be upon him, and for a period during his time, did not have latrines in their homes. Instead, they would relieve themselves in the open wilderness. As for the "ḥammām," it is a place designated for bathing. The people of Medina did not have hammams during the time of the Prophet, peace and blessings be upon him. The means of removing dirt and impurities at that time were soap, sidr, and similar substances, not shampoo, as it is a recently manufactured product.
