Narrated Zainab: (daughter of Um Salama) that her mother said, "While I was (lying) with Allah's Apostle underneath a woolen sheet, I got the menstruation, and then slipped away and put on the clothes (which I used to wear) in menses. He asked, "What is the matter? Did you get your menses?" I replied in the affirmative and then entered underneath that woolen sheet. I and Allah's Apostle used to take a bath from one water pot and he used to kiss me while he was fasting."

And Abdullah bin Umar (may Allah be pleased with them both) moistened a cloth and placed it on his body while he was fasting, and Sha’bi was fasting but went to the bathhouse (for bathing), and Ibn Abbas (may Allah be pleased with them both) said that there is no harm in tasting a pot or anything (by placing it on the tongue) to know its taste. Hasan al-Basri (may Allah have mercy on him) said that there is no objection for the fasting person to rinse the mouth or to seek coolness, and Ibn Mas’ud (may Allah be pleased with him) said that when someone intends to fast, he should get up in the morning with oil applied and hair combed, and Anas (may Allah be pleased with him) said that I have a «ابزن» (a stone basin) in which I immerse myself even though I am fasting. It is narrated from the Prophet (peace and blessings of Allah be upon him) that he used the miswak while fasting, and Abdullah bin Umar (may Allah be pleased with them both) said that he used to use the miswak during the day, morning and evening (at all times), and the fasting person should not swallow saliva, and Ata’ (may Allah have mercy on him) said that if saliva comes out, I do not say that his fast is broken, and Ibn Sirin (may Allah have mercy on him) said that there is no harm in using a wet miswak. Someone said that there is a taste in it, so he replied: Is there not a taste in water? Even though you rinse your mouth with it. Anas, Hasan, and Ibrahim said that it is permissible for the fasting person to apply kohl.
