Hadith on Hawd: The Prophet recognizes believers at the Fountain

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, my fountain is wider than the distance between Aylah and Eden. Its water is whiter than ice, sweeter than honey and milk. Its cups are more numerous than the stars. Verily, I will block some people from it, just as a man blocks camels from his fountain.” They said, “O Messenger of Allah, will you recognize us on that Day?” The Prophet said, “Yes, you will have marks which no one among people will have but you. You will come to me with a blazing forehead and bright hands and feet from the traces of ablution.”

عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ حَوْضِي أَبْعَدُ مِنْ أَيْلَةَ مِنْ عَدَنٍ لَهُوَ أَشَدُّ بَيَاضًا مِنْ الثَّلْجِ وَأَحْلَى مِنْ الْعَسَلِ بِاللَّبَنِ وَلَآنِيَتُهُ أَكْثَرُ مِنْ عَدَدِ النُّجُومِ وَإِنِّي لَأَصُدُّ النَّاسَ عَنْهُ كَمَا يَصُدُّ الرَّجُلُ إِبِلَ النَّاسِ عَنْ حَوْضِهِ قَالُوا يَا رَسُولَ اللَّهِ أَتَعْرِفُنَا يَوْمَئِذٍ قَالَ نَعَمْ لَكُمْ سِيمَا لَيْسَتْ لِأَحَدٍ مِنْ الْأُمَمِ تَرِدُونَ عَلَيَّ غُرًّا مُحَجَّلِينَ مِنْ أَثَرِ الْوُضُوءِ
