Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: Allah Almighty does not accept the prayer of any one of you who is in a state of impurity until he performs ablution.

Sayyiduna ‘Uthman bin ‘Affan (may Allah be pleased with him) asked (Humran) for a vessel of water. (And after receiving it, first) he poured water on his palms three times, then washed them. After that, he put his right hand into the vessel and (taking water) rinsed his mouth and cleaned his nose, then washed his face three times. And washed both hands up to the elbows three times. Then he wiped his head. Then he washed both feet up to the ankles three times. Then he said that the Messenger of Allah (peace and blessings of Allah be upon him) said:“Whoever performs ablution like this of mine and then offers two rak‘ahs in which he does not talk to himself, his past sins are forgiven.”

It was asked from Sayyiduna Abdullah bin Zaid (may Allah be pleased with him) about the ablution of the Messenger of Allah (peace and blessings be upon him), so he called for a basin of water. And he performed ablution for them just as the Messenger of Allah (peace and blessings be upon him) used to do. (First) he poured water from the basin onto his hands, then washed his hands three times, then put his hand into the basin (and took water), then rinsed his mouth, put water into his nose, and cleaned his nose, with three handfuls. Then he put his hand into the basin, cleaned his nose, with three handfuls. Then he put his hand into the basin and washed his face three times. Then he washed both his hands up to the elbows twice. Then he put his hand into the basin and wiped his head. (First) he brought (his hands) forward, then took them back, once. Then he washed both his feet up to the ankles.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever performs ablution should clean his nose, and whoever uses stones for istinja should do so with an odd number (i.e., one, three, or five).

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: When any one of you wakes up from sleep and performs ablution, he should blow his nose three times, for the devil spends the night in the upper part of his nose.

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said that during a journey which we undertook (in the company of the Messenger of Allah, peace and blessings be upon him), the Prophet (peace and blessings be upon him) lagged behind us (this journey was from Makkah to Madinah), and he joined us when the time for (‘Asr) prayer had arrived. We were performing ablution (hurriedly), so instead of washing our feet thoroughly, we were just passing water over them. (Seeing this condition) the Prophet (peace and blessings be upon him) called out in a loud voice:“Woe to the heels from the Fire!”two or three times he (peace and blessings be upon him) said this in a loud voice.

Once, Sayyiduna Abu Hurairah (may Allah be pleased with him) passed by and people were performing ablution with a water jug. He said, "Perform ablution thoroughly, for Abu al-Qasim (peace and blessings be upon him) said: 'Woe to the heels from the fire (of Hell).'"

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that I heard the Messenger of Allah (peace and blessings be upon him) saying: "On the Day of Resurrection, my Ummah will be called with bright foreheads and bright hands and feet due to the marks of ablution. Therefore, whoever among you can increase his brightness, let him do so." (i.e., perform ablution thoroughly)

Syedna Abu Huraira (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: If I had not feared hardship for my ummah or for the people, I would have commanded the use of the miswak for every prayer.

Sayyiduna Abu Musa (may Allah be pleased with him) narrates that I once came to the Messenger of Allah (peace and blessings of Allah be upon him) and found him using a miswak with his hand, and a sound of "ugh" was coming from his mouth, and the miswak was in his mouth as if he were about to vomit.
