✍ Answered by: Al-Bāḥith Kāmrān Ilāhī Ẓahīr ḥafiẓahullāh
❓ Question:
What is the modern equivalent weight of one mudd and one ṣāʿ according to Islamic teachings?
📚 Definitions Based on Ḥadīth and Fiqh
➤ Definition of Mudd (مدّ):
According to Mirqāt al-Ṣuʿūd:
✔ A mudd is the amount that fills both hands cupped together with grain or similar substance.
✔ Four such mudd make one ṣāʿ.
➤ Definition of Ṣāʿ (صاع):
As per Qāmūs, a ṣāʿ equals:
✔ 4 mudd
✔ Each mudd is approximately 1⅓ Ratl (a historical weight unit)
⚖ Standardized Modern Weight
Based on experiments and comparisons with the Prophetic ṣāʿ, scholars have derived approximate modern equivalents:
✔ 1 Mudd ≈ 650 grams
✔ 1 Ṣāʿ = 4 × 650g = 2.6 kilograms
📌 Clarification:
Due to the unavailability of the exact Prophetic ṣāʿ in all regions, jurists used grain and common food items to estimate the volume.
✔ Renowned lexicographers and scholars tested these measurements and confirmed their alignment with the ṣāʿ of the Prophet ﷺ.
✅ Conclusion:
✔ 1 Mudd = Approx. 650 grams
✔ 1 Ṣāʿ = Approx. 2.6 kilograms
