As-Sa'ib bin Yazid said, The Sa' at the time of the Prophet (ﷺ) was equal to one Mudd plus one-third of a Mudd of your time, and then it was increased in the time of Caliph `Umar bin `Abdul `Aziz.

':'Telah menceritakan kepada kami Utsman bin Abi Syaibah telah menceritakan kepada kami Al Qasim bin Malik Al Muzanni telah menceritakan kepada kami Al Ju'aid bin Abdurrahman dari As Sa`ib bin Yazid mengatakan; Satu sha' di jaman Nabi shallallahu 'alaihi wasallam adalah setara satu mud ditambah sepertiga mud kalian sekarang kemudian di jaman Umar bin Abdul 'Aziz ditambah lagi.'

Ibn `Umar used to give the Zakat of Ramadan (Zakat-al-Fitr) according to the Mudd of the Prophet, the first Mudd, and he also used to give things for expiation for oaths according to the Mudd of the Prophet. Abu Qutaiba said, Malik said to us, 'Our Mudd (i.e., of Medina) is better than yours and we do not see any superiority except in the Mudd of the Prophet!' Malik further said, to me, 'If a ruler came to you and fixed a Mudd smaller than the one of the Prophet, by what Mudd would you measure what you give (for expiation or Zakat-al-Fitr?' I replied, 'We would give it according to the Mudd of the Prophet' On that, Malik said, 'Then, don't you see that we have to revert to the Mudd of the Prophet ultimately?'

':'Telah menceritakan kepada kami Mundzir bin Walid Al Jarudi telah menceritakan kepada kami Abu Qutaibah yakni Salam telah menceritakan kepada kami Malik dari Nafi' mengatakan Ibnu Umar membayar zakat Ramadhan dengan takaran mud Nabi shallallahu 'alaihi wasallam yaitu mud di masa permulaan dan membayar kaffarat sumpah dengan ukuran mud Nabi shallallahu 'alaihi wasallam. Abu Qutaibah berkata; Malik mengatakan kepada kami; 'mud kami jauh lebih besar daripada mud kalian dan kami sependapat tak ada tambahan selain pada mud Nabi shallallahu 'alaihi wasallam.' Sedang Malik mengatakan kepadaku; 'Kalau seorang amir datang kepada kalian kemudian menetapkan ukuran mudd yang jauh lebih kecil daripada mudd Nabi shallallahu 'alaihi wasallam dengan takaran mana kalian membayarnya? ' aku menjawab 'kami membayarnya dengan takaran mudd Nabi shallallahu 'alaihi wasallam.' ia mengatakan; 'Bukankah kamu sependapat bahwa urusan hanyasanya kembali kepada mudd Nabi shallallahu 'alaihi wasallam? ''

Allah's Messenger (ﷺ) said, O Allah! Bestow Your Blessings on their measures, Sa' and Mudd (i.e., of the people of Medina).

':'Telah menceritakan kepada kami Abdullah bin Yusuf telah mengabarkan kepada kami Malik dari Ishaq bin Abdullah bin Abu Thalhah dari Anas bin Malik bahwasanya Rasulullah Shallallahu'alaihiwasallam pernah memanjatkan doa: 'Ya Allah berilah mereka barakah dalam takaran mereka sha' mereka dan mud mereka.''
