Nu'aim b. 'Abdullah al-Mujmir reported
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.
Nu'aim b. 'Abdallah reported
He saw Abu Huraira perform ablution. He washed his face and washed his hands up to the arms. He then washed his feet and reached up to the shanks and then said: I heard Allah's Messenger (ﷺ) say: My people would come with bright faces and bright hands and feet on account of the marks of ablution, so he who can increase the lustre of his forehead (and that of his hands and legs) should do so.
Abu Huraira reported
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.
Abu Huraira reported the Messenger of Allah (ﷺ) said
My people would come to me on the Cistern and I would drive away persons (from it) just as a person drives away other people's camels from his camels. They (the hearers) said: Apostle of Allah, would you recognize us? He replied: Yea, you would have a mark which other people will not have. You would come to me with a white blaze on your foreheads and white marks on your feet because of the traces of ablution. A group among you would be prevented from coming to me, and they would not meet me, and I would say: O my Lord, they are my companions. Upon this an angel would reply to me saying: Do you know what these people did after you.
Hudhaifa reported
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).
Abu Huraira reported
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.
Abu Huraira reported
The Messenger of Allah (may peace The upon him) went out to the graveyard and said: Peace be upon you, the abode of the believing people. and If Allah so wills we shall join you.... (and so on and so forth) like the hadith narrated by Isma'il b. Ja'far except the words of Malik: Then some persons would be driven away from my Cistern.
