BAYHAQI 9710:
from al-Juʿayd / Ibn ʿAbd al-Raḥman —
[Machine] The traveler said to me, "During the time of the Prophet Muhammad ﷺ, the measurement of a sa' was a certain amount, and one-third of that measurement is what you have today. It was increased during the time of Umar ibn Abdul Aziz." The traveler continued, "I performed Hajj along with the Prophet ﷺ when I was a young boy."

عن الجعيد / ابن عبد الرحمن —
قَالَ لِي السَّائِبُ كَانَ الصَّاعُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ مُدًّا وَثُلُثَ مُدِّكُمُ الْيَوْمَ فَزِيدَ فِيهِ فِي زَمَنِ عُمَرَ بْنِ عَبْدِ الْعَزِيزِ قَالَ السَّائِبُ وَحُجَّ بِي فِي ثَقَلِ النَّبِيِّ ﷺ وَأَنَا غُلَامٌ
