It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When one of you uses stones for cleansing (istinja), let him use an odd number, for Allah is Witr (One) and loves what is odd. Do you not see that the heavens are seven, the earths are seven, and the circumambulation (tawaf) too (is of seven circuits)?" And he (peace and blessings be upon him) mentioned several things. This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but the two Shaykhs did not record it with this wording. They agreed only on "Whoever uses stones, let him use an odd number."

Sayyidah Aishah (may Allah be pleased with her) narrates that when the Messenger of Allah (peace and blessings be upon him) came out after relieving himself, he would say: 'Ghufranak' ((O Allah,) I seek Your forgiveness).

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) came out of the toilet, he would say: 'Ghufranak' ((O Allah,) I seek Your forgiveness). This hadith is sahih (authentic), because Yusuf bin Abi Burdah is among the trustworthy narrators of the family of Abu Musa, and his father's hearing from Sayyidah Aishah (may Allah be pleased with her) is established.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that one of the pure wives of the Prophet (peace and blessings be upon him) performed the ritual bath (ghusl) for janabah (major ritual impurity), and then the Prophet (peace and blessings be upon him) performed ablution or the ritual bath with her (left-over) water.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) intended to perform ablution from a vessel, and one of his (peace and blessings be upon him) pure wives said: O Messenger of Allah! I have already performed ablution from this (water). So he (peace and blessings be upon him) performed ablution and said: "Nothing makes water impure." This hadith is sahih (authentic) in the chapter of purification. Imam Bukhari used Ikrimah as evidence and Imam Muslim used Simak bin Harb as evidence, and no hidden defect ('illah) is in it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) was asked about the circumstances of the expedition of Tabuk (the Hour of Hardship), and he said: We set out for Tabuk in intense heat. At one place we were struck by such severe thirst that we felt our necks would be severed, to the extent that a man would slaughter his camel, squeeze its stomach contents and drink (the fluid), and place the rest over his liver. Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: O Messenger of Allah! Allah Almighty has always placed good in your supplications, so supplicate for us. He (peace and blessings be upon him) asked: "Would you like that?" He said: Yes. So he (peace and blessings be upon him) raised his hands, and he had not yet lowered them when clouds covered the sky and such rain fell that everyone filled their vessels. Then we looked and saw that the rain had not gone beyond the bounds of the army. This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, and it contains this point of fiqh: the fluid of the stomach contents of a lawful animal does not make water impure.

Kabshah bint Ka'b bin Malik (may Allah be pleased with her), who was the wife of Abu Qatadah's son, narrates that Sayyiduna Abu Qatadah (may Allah be pleased with him) came to her and she poured out water for his ablution. Just then a cat came and began to drink from it, and Abu Qatadah tilted the vessel towards it until it had drunk. Kabshah says: He saw me looking at him in surprise and said: "O my niece! Are you surprised?" I said: Yes. So he said: The Messenger of Allah (peace and blessings be upon him) said: "It (the cat) is not impure; it is like those (servants) who go about around you." This hadith is sahih (authentic), and Imam Malik also cited it as evidence in al-Muwatta.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said about the cat: "It is not impure; it is like one of the members of the household." What is contrary to this has been authenticated on the condition of Imam Bukhari and Imam Muslim, and they did not record that either.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The purification of your vessel, when a dog has licked from it, is that it be washed seven times, the first of them with earth; and the ruling for a cat is the same." This hadith has a sahih (authentic) chain and is on the condition of Imam Bukhari and Imam Muslim, and the narrator Abu Bakrah is trustworthy and reliable.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The purification of a vessel, when a dog has licked from it, is that it be washed seven times, the first with earth; and for a cat (licking from it) it should be washed once or twice." The narrator Qurrah was in doubt (about the words 'once or twice').
