We were with the Messenger of Allah ﷺ. He said when we arrived at a halting place: You are not a hundred thousandth part of those who will come down to me at the pond. I (the narrator AbuHamzah) asked: What was your number that day? He replied: Seven or eight hundred. (Using translation from Abū Dāʾūd 4746)
سَمِعْتُ زَيْدَ بْنَ أَرْقَمَ يَقُولُ كُنَّا مَعَ رَسُولِ اللهِ ﷺ فَقَالَ «أَنْتُمْ جُزْءٌ مِنْ مِائَةِ أَلْفِ جُزْءٍ مِمَّنْ يَرِدُ عَلَيَّ الْحَوْضَ» قُلْتُ كَمْ كُنْتُمْ يَوْمَئِذٍ؟ قَالَ «سَبْعُمِائَةِ رَجُلٍ أَوْ ثَمَانِمِائَةٍ رَجُلٍ»
