Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "Whoever performs ablution should clean his nose, and whoever uses stones for istinja should use an odd number (of stones)."

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When any one of you performs ablution, he should put water into his nose and then clean it, and whoever uses stones for istinja, he should do so with an odd number (of stones), and when any one of you wakes up from his sleep, he should wash his hand before putting it into the water for ablution, because none of you knows where his hand has been (on which parts of his body it has passed) during the night."

Ibn Huraij said to (Sayyiduna) Abdullah bin Umar (may Allah be pleased with them): "I have seen that (during Tawaf) you do not touch any corner except the two Yemeni corners, and I have seen that you wear Sabti sandals, and I have seen that you dye (your hair or clothes) with yellow color, and I have seen that when you are in Makkah, other people, as soon as they see the (crescent of Dhul-Hijjah), put on Ihram, but you do not put on Ihram until the day of Tarwiyah (the 8th of Dhul-Hijjah)." So Abdullah bin Umar (may Allah be pleased with them) replied: "Indeed, I do these things. As for touching the Yemeni corners during Tawaf, I have not seen the Messenger of Allah (peace and blessings be upon him) touch any corner except these two Yemeni corners. As for the Sabti sandals, indeed, I saw the Messenger of Allah (peace and blessings be upon him) wearing such sandals that had no hair on them, and he would perform ablution in those sandals (i.e., he would wash his feet, not wipe over them). Therefore, I like to wear such sandals. As for the yellow color, indeed, I saw the Messenger of Allah (peace and blessings be upon him) dyeing with it. Therefore, I like to dye with it. And as for putting on Ihram, I did not see the Messenger of Allah (peace and blessings be upon him) put on Ihram until his mount moved (i.e., on the eighth day)."

Umm al-Mu'minin Aisha Siddiqa (may Allah be pleased with her) says that the Prophet Muhammad (peace and blessings be upon him) liked to start with the right side in wearing shoes, combing his hair, performing purification (wudu, ghusl), and (in fact, in all matters).

Narrated Anas bin Malik (may Allah be pleased with him): I saw the Messenger of Allah (peace and blessings of Allah be upon him) when the time for prayer had come and people searched for water for ablution but could not find any. Then water for ablution was brought to the Messenger of Allah (peace and blessings of Allah be upon him) in a vessel. He (peace and blessings of Allah be upon him) placed his hand in that vessel and ordered the people: "Perform ablution with this." Anas (may Allah be pleased with him) says: I saw water gushing forth from between the fingers of the Messenger of Allah (peace and blessings of Allah be upon him) until all the people had performed ablution.

And Sayyiduna Anas (may Allah be pleased with him) also narrates that when the Messenger of Allah (peace and blessings of Allah be upon him) had his head shaved, Abu Talha (may Allah be pleased with him) was the first to take the hair of the Prophet (peace and blessings of Allah be upon him).

Narrated from Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When a dog drinks water or anything else from someone's vessel, he should wash it seven times."

Narrated Abdullah bin Umar (may Allah be pleased with them): During the time of Allah's Messenger (peace be upon him), dogs used to come and go in the mosque, and sometimes they would urinate there, but the people did not sprinkle water or anything (to clean) because of their coming and going.

Narrated Abu Huraira (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) said: "A servant remains in the state of prayer as long as he is waiting for the prayer in the mosque, unless he loses his ablution."

Sayyiduna Zaid bin Khalid (may Allah be pleased with him) asked the Commander of the Faithful, Uthman bin Affan (may Allah be pleased with him), "Tell me, if (a person) has intercourse but there is no ejaculation, what is the ruling?" So Sayyiduna Uthman (may Allah be pleased with him) said, "He should perform ablution as he does for prayer and wash his private part." Sayyiduna Uthman (may Allah be pleased with him) says, "I heard this issue from the Messenger of Allah (peace and blessings of Allah be upon him)." (Sayyiduna Zaid (may Allah be pleased with him), the narrator of the hadith, says that) then I asked this issue to Ali, Zubair, Talha, and Ubayy bin Ka'b (may Allah be pleased with them), and they (also) gave the same ruling to that person.
