Chapter 273 | The meaning of the ssaa’ and mudd, and the difference between the ssaa’ and mudd’ of water, and the ssaa’ and mudd of food
وبهذا الاسناد، عن محمد بن أحمد، عن جعفر بن إبراهيم بن محمد الهمداني - قال: وكان معنا حاجا - قال: كتبت إلى أبي الحسن عليه السلام على يد أبي: جعلت فداك إن أصحابنا اختلفوا في الصاع، بعضهم يقول: الفطرة بصاع المدينة، وبعضهم يقول: بصاع العراق. فكتب إلي: الصاع ستة أرطال بالمدني وتسعة أرطال بالعراقي. قال: وأخبرني فقال: إنه بالوزن يكون ألفا ومائة وسبعين وزنا.
2. With this chain of narrators, from Muhammed bin Ahmad, from Ja’far bin Ibrahim bin Muhammed al-Hamdani, that he said, and he was with us, performing pilgrimage. He said: I wrote to Abu’l-Hasan, peace be upon him, on the hands of my father: May I be sacrificed for you, our companions have disputed with regards to (the measurement of) a ssaa’. Some of them say that (the alms tax of) the Fitra is (given by the amount of) a ssaa’ of Medina, and some of them say the ssaa’ of Iraq. Then he wrote to me: A ssaa’ is (consisting of) six pounds by the Medinian standard, and nine pounds by the Iraqi standard. He said: He also informed me and said: In measurement, it is one thousand and one hundred and seventy measures.
