The Prophet ﷺ said, "I am your predecessor (forerunner) at the Lake-Fount, and whoever will pass by there, he will drink from it and whoever will drink from it, he will never be thirsty. There will come to me some people whom I will recognize, and they will recognize me, but a barrier will be placed between me and them."
قَالَ النَّبِيُّ ﷺ إِنِّي فَرَطُكُمْ عَلَى الْحَوْضِ مَنْ مَرَّ عَلَىَّ شَرِبَ وَمَنْ شَرِبَ لَمْ يَظْمَأْ أَبَدًا لَيَرِدَنَّ عَلَىَّ أَقْوَامٌ أَعْرِفُهُمْ وَيَعْرِفُونِي ثُمَّ يُحَالُ بَيْنِي وَبَيْنَهُمْ
