The Messenger of Allah (ﷺ) said: Five prayers and from one Friday prayer to (the next) Friday prayer is an expiation (of the sins committed in between their intervals) if major sins are not committed.
We were entrusted with the task of tending the camels. On my turn when I came back in the evening after grazing them in the pastures, I found Allah's Messenger (ﷺ) stand and address the people. I heard these words of his: If any Muslim performs ablution well, then stands and prays two rak'ahs setting about them with his heart as well as his face, Paradise would be guaranteed to him. I said: What a fine thing is this! And a narrator who was before me said: The first was better than even this. When I cast a glance, I saw that it was 'Umar who said: I see that you have just come and observed: If anyone amongst you performs the ablution, and then completes the ablution well and then says: I testify that there is no god but Allah and that Muhammad is the servant of Allah and His Messenger, the eight gates of Paradise would be opened for him and he may enter by whichever of them he wishes.
It was said to him (by people): Perform for us the ablution (as it was performed) by the Messenger of Allah (way peace be upon him). He ('Abdullah b. Zaid) called for a vessel (of water), and poured water from it on his hands and washed them three times. Then he inserted his hand (in the vessel) and brought it (water) out, rinsed his mouth and snuffed up water from the palm of one hand doing that three times, He again inserted his hand and brought it out and washed his face three times, then inserted his hand and brought it out and washed each arm up to the elbow twice, then inserted his hand and brought it out and wiped his head both front and back with his hands. He then washed his feet up to the ankles, and then said: This is how God's Messenger (peace be upon him) performed ablution.
He saw Allah's Messenger (ﷺ) perform the ablution. He rinsed his mouth then cleaned his nose, then washed his face three times, then washed his right hand thrice and then the other one, thrice. He then took fresh water and wiped his head and then washed his feet till he cleaned them.
When anyone wipes himself with pebbles (after answering the call of nature) he must make use of an odd number and when any one of you performs ablution he must snuff in his nose water and then clean it.
The Apostle of Allah (ﷺ) said. When any one of you awakes up from sleep and performs ablution, he must clean his nose three times, for the devil spends the night in the interior of his nose.

Salim, the freed slave of Shaddad, said:
حَدَّثَنَا هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، وَأَبُو الطَّاهِرِ، وَأَحْمَدُ بْنُ عِيسَى، قَالُوا أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، عَنْ مَخْرَمَةَ بْنِ بُكَيْرٍ، عَنْ أَبِيهِ، عَنْ سَالِمٍ، مَوْلَى شَدَّادٍ قَالَ دَخَلْتُ عَلَى عَائِشَةَ زَوْجِ النَّبِيِّ صلى الله عليه وسلم يَوْمَ تُوُفِّيَ سَعْدُ بْنُ أَبِي وَقَّاصٍ فَدَخَلَ عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرٍ فَتَوَضَّأَ عِنْدَهَا فَقَالَتْ يَا عَبْدَ الرَّحْمَنِ أَسْبِغِ الْوُضُوءَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ
" وَيْلٌ لِلأَعْقَابِ مِنَ النَّارِ " .
I came to 'A'isha, the wife of the Prophet (ﷺ), on the day when Sa'db. Abi Waqqas died. 'Abd al-Rahman b. Abu Bakr also came there and he performed ablution in her presence. She (Hadrat 'A'isha) said: Abd al-Rahman, complete the ablution as I heard the Allah's Messenger (ﷺ) say: Woe to the heels because of hell-fire.

'Abdullah b. 'Amr reported:
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، ح وَحَدَّثَنَا إِسْحَاقُ، أَخْبَرَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ هِلاَلِ بْنِ يِسَافٍ، عَنْ أَبِي يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ رَجَعْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم مِنْ مَكَّةَ إِلَى الْمَدِينَةِ حَتَّى إِذَا كُنَّا بِمَاءٍ بِالطَّرِيقِ تَعَجَّلَ قَوْمٌ عِنْدَ الْعَصْرِ فَتَوَضَّئُوا وَهُمْ عِجَالٌ فَانْتَهَيْنَا إِلَيْهِمْ وَأَعْقَابُهُمْ تَلُوحُ لَمْ يَمَسَّهَا الْمَاءُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" وَيْلٌ لِلأَعْقَابِ مِنَ النَّارِ أَسْبِغُوا الْوُضُوءَ " .
We returned from Mecca to Medina with the Messenger of Allah (ﷺ), and when we came to some water on the way, some of the people were in a hurry at the time of the afternoon prayer and performed ablution hurriedly; and when we reached them, their heels were dry, no water had touched them. The Prophet (ﷺ) said: Woe to (dry) heels, because of Hell-fire. Make your ablution thorough.
'Umar b. Khattab said that a person performed ablution and left a small part equal to the space of a nail (unwashed). The Apostle of Allah (ﷺ) saw that and said: Go back and perform ablution well. He then went back (performed ablution well) and offered the prayer.
Allah's Messenger (ﷺ) said: When a bondsman-a Muslim or a believer-washes his face (in course of ablution), every sin he contemplated with his eyes, will be washed away from his face along with water, or with the last drop of water; when he washes his hands, every sin they wrought will be effaced from his hands with the water, or with the last drop of water; and when he washes his feet, every sin towards which his feet have walked will be washed away with the water or with the last drop of water with the result that he comes out pure from all sins.
The Messenger of Allah (way peace be upon him) said: He who performed ablution well, his sins would come out from his body, even coming out from under his nails.
I saw Abu Huraira perform ablution. He washed his face and washed it well. He then washed his right hand including a portion of his arm. He then washed his left hand including a portion of his arm. He then wiped his head. He then washed his right foot including his shank, and then washed his left foot including shank, and then said: This is how I saw Allah's Messenger (ﷺ) perform his ablution. And (Abu Huraira) added that the Messenger of Allah (ﷺ) had observed: You shall have your faces hands and feet bright on the Day of Resurrection because of your perfect ablution. He who can afford among you, let him increase the brightness of his forehead and that of hands and legs.
Verily Allah's Messenger (ﷺ) said: My Cistern has its dimensions wider than the distance between Aila and Aden, and its water is whiter than ice and sweeter than the honey diluted with milk, and its cups are more numerous than the numbers of the stars. Verily I shall prevent the (faithless) people therefrom just as a man prevents the camels of the people from his fountain. They said: Messenger of Allah, will you recognise us on that day? He said: Yes, you will have distinctive marks which nobody among the peoples (except you) will have; you would come to me with blazing forehead and bright hands and feet on account of the traces of ablution.
The Messenger of Allah (ﷺ) said: My Cistern is bigger than the space between Aila and Aden. By Him in Whose Hand is my life, I will drive away persons (from it) just as a person drives away unknown camels from his cistern. They (the companions) said: Messenger of Allah, would you recognise us? He said: Yes, you would come to me with white faces, and white hands and feet on account of the traces of ablution. None but you would have (this mark).
The Messenger of Allah (ﷺ) came to the graveyard and said: "Peace be upon you! The abode of the believing people and we, if God so wills, are about to join you. I love to see my brothers." They (the hearers) said: Aren't we your brothers, O Messenger of Allah? He said: You are my companions, and our brothers are those who have, so far, not come into the world. They said: Messenger of Allah, how would you recognise those persons of your Ummah who have not yet been born? He said: Supposing a man had horses with white blazes on foreheads and legs among horses which were all black, tell me, would he not recognise his own horses? They said: Certainly, O Messenger of Allah. He said: They would come with white faces and arms and legs owing to ablution, and I would arrive at the Cistern before them. Some people would be driven away from my Cistern as the stray camel is driven away. I would call out: Come, come. Then it would be said (to me): These people changed themselves after you, and I would say: Be off, be off.
I was (standing) behind Abu Huraira and he was performing the ablution for prayer. He extended the (washing) of his hand that it went up to his armpit. I said to him: O Abu Huraira, what is this ablution? He said: O of the tribe of Faruukh, you are here; if I knew that you were here, I would have never performed ablution like this; I have heard my Friend (ﷺ) say. In a believer adornment would reach the places where ablution reaches.
The Messenger of Allah (ﷺ) said: Should I not suggest to you that by which Allah obliterates the sins and elevates the ranks (of a man). They (the hearers) said: Yes, Messenger of Allah. He said: Performing the ablution thoroughly despite odds, tranverside of more paces towards the mosque, and waiting for the next prayer after observing a prayer, and that is mindfulness.
The Apostle (ﷺ) said: Were it not that I might over-burden the believers-and in the hadith transmitted by Zuhair" people" -I would have ordered them to use toothstick at every time of prayer.

Chapter 15: Siwak (tooth-stick) - كتاب الطهارة
Ibn 'Abbas reported that he spent a night at the house of the Messenger of Allah (ﷺ), The Apostle of Allah (way peace be upon him) got up for prayer in the latter part of the night. He went out and looked towards the sky and then recited this verse (190th) of AI-i-'Imran:
" Verily in the creation of the heavens and the earth and the alternation of night and day." up to the (words)" save us from the torment of Hell."

He than lay down on the bed. and again got up and went out and looked towards the sky and recited this verse (mentioned above), then returned, used the tooth-stick, performed ablution and again offered the prayer.
Five are the acts quite akin to the Fitra, or five are the acts of Fitra: circumcision, shaving the pubes, cutting the nails, plucking the hair under the armpits and clipping the moustache.
