Sayyiduna Abdullah bin Abu Qatadah (may Allah be pleased with him) narrates from his father that water for ablution was placed for him, and a cat drank from it, but he began to perform ablution with it. People said: "O Abu Qatadah! The cat has drunk from it," he said: "I heard the Messenger of Allah (peace and blessings be upon him) say: The cat is from among the household, and it is among those who go around you (males and females) frequently."

Under this chapter, the following sub-chapters and hadiths have been mentioned.

It is narrated from Sayyida Asma bint Abu Bakr (may Allah be pleased with her), she says that a woman came to the Noble Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! Menstrual blood gets on a woman," the Messenger of Allah (peace and blessings be upon him) said: "She should scrape it off, then wash it with water, and then she may pray in it."

It is narrated from Sayyidah Umm Qais bint Mihsan (may Allah be pleased with her), she says: I asked the Messenger of Allah (peace and blessings be upon him) about menstrual blood that gets on clothes. He (peace and blessings be upon him) said: "Wash it with water and lotus leaves, and scrape it off with a bone."

Ibrahim bin Abdur Rahman bin Awf’s umm walad (may Allah have mercy on her) says:“I used to drag my garment,”and in another narration:“I was a woman whose garment’s lower part was long, and when I would come to the mosque, I would pass through both impure and pure places.”So I went to Sayyida Umm Salamah (may Allah be pleased with her) and asked her about this. She said that the Messenger of Allah (peace and blessings be upon him) said:“The latter (pure) place will purify it.”

Musa bin Abdullah, may Allah have mercy on him, who was a truthful man, narrates from a female Companion from Banu Abd Ashhal, may Allah be pleased with her, she says: I said, "O Messenger of Allah! The path we take to the mosque is foul-smelling; what should we do when it rains?" He (peace and blessings be upon him) said: "Is there not a clean path after that?" She said: "Yes, of course." He (peace and blessings be upon him) said: "Then that path is in place of this one." In another narration, he (peace and blessings be upon him) said: "This clean path will remove the effect (of impurity) of that (unclean path)."

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) led the prayer and (during the prayer) removed his shoes, so the people also removed their shoes. When the Prophet (peace and blessings be upon him) finished, he asked: "Why did you people remove your shoes?" They said: "O Messenger of Allah! We saw you removing your shoes, so we also removed ours." The Prophet (peace and blessings be upon him) said: "Jibril (peace be upon him) came to me and informed me that there was impurity on my shoes. Therefore, when any one of you comes to the mosque, he should turn his shoes over and check them. If he sees any impurity on them, he should clean it off with the ground and then pray in them."

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that a Bedouin entered the mosque and, after performing two units of prayer, made this supplication: "O Allah! Have mercy on me and on Muhammad (peace be upon him), and do not have mercy on anyone else along with us." The Noble Prophet (peace be upon him) turned towards him and said: "You have made something vast into something narrow." Soon after, this Bedouin began to urinate in the mosque, so the people rushed towards him, but the Messenger of Allah (peace be upon him) instructed them: "You have only been sent to make things easy for people, not to make things difficult. Pour a bucket of water over this urine."

(Second chain) A Bedouin entered the mosque while the Messenger of Allah, peace and blessings be upon him, was present there. He supplicated, saying: "O Allah! Forgive me and Muhammad, peace and blessings be upon him, and do not forgive anyone else along with us." The Prophet, peace and blessings be upon him, smiled and said: "You have made something vast into something narrow." Then he walked away, and when he reached a corner of the mosque, he spread his legs and began to urinate. The Messenger of Allah, peace and blessings be upon him, stood up and said: "This house has been made solely for the remembrance of Allah and for prayer; urination is not to be done in it." Then the Prophet, peace and blessings be upon him, called for a bucket of water and poured it over the spot. After understanding the religion, the Bedouin used to say: "The Prophet, peace and blessings be upon him, stood towards me—may my parents be sacrificed for him—he neither spoke harshly to me, nor scolded me, nor hit me."
