Abu Hurairah (RA) reported: Verily Allah's Messenger ( صلی اللہ علیہ وسلم ) 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 Hurairah (RA) reported the Messenger of Allah ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ) , 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.

This hadith has been transmitted by Ibn Mughira on the authority of his father by another chain of transmitters.

Bakr reported that he had heard from the son of Mughira that verily the Apostle of Allah ( صلی اللہ علیہ وسلم ) performed ablution and wiped over his forehead and wiped over his turban and over his socks.
