Sahih al-Bukhari 7330
Holding Fast to the Qur'an and Sunnah
The religious learned men should not differ
حَدَّثَنَا عَمْرُو بْنُ زُرَارَةَ، حَدَّثَنَا الْقَاسِمُ بْنُ مَالِكٍ، عَنِ الْجُعَيْدِ، سَمِعْتُ السَّائِبَ بْنَ يَزِيدَ، يَقُولُ كَانَ الصَّاعُ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم مُدًّا وَثُلُثًا بِمُدِّكُمُ الْيَوْمَ، وَقَدْ زِيدَ فِيهِ. سَمِعَ الْقَاسِمُ بْنُ مَالِكٍ الْجُعَيْدَ
Narrated As-Sa'ib bin Yazid: The Sa' (a kind of measure) during the lifetime of the Prophet (ﷺ) used to be equal to the one Mudd (another kind of measure) and one third of a Mudd which we use today, but the Sa' of today has become large.
