وَعَنْ زَيْدِ بْنِ أَرْقَمَ قَالَ: كُنَّا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَنَزَلْنَا منزلا فَقَالَ: «مَا أَنْتُمْ جُزْءٌ مِنْ مِائَةِ أَلْفِ جُزْءٍ مِمَّنْ يَرِدُ عَلَى الْحَوْضِ» . قِيلَ: كَمْ كُنْتُمْ يَوْمَئِذٍ؟ قَالَ: سَبْعَمِائَةٍ أَوْ ثَمَانِمِائَةٍ. رَوَاهُ أَبُو دَاوُد

Zaid b. Aqram told that when they were with God’s messenger he said when they arrived at a halting place, “You are not a hundred thousandth part of those who will come down to the pond.” He was asked what their number was that day and replied that it was seven or eight hundred. Abu Dawud transmitted it.
