2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from abu Yahya al-Wasitiy in a marfu‘ manner has the following: “’Amir al-Mu’minin (a.s.), once passed by the butchers’ market and prohibited the selling of seven items in a sheep. He (the Imam) prohibited the selling of blood, glands, ears of the heart, the spleen, spinal cord, testicles and penis. Certain one of the butchers said, ‘O ’Amir al-Mu’minin, liver and spleen’ are not different. They are the same thing.’ ‘You suffer from a lack of understanding and what you say is not true’ ’Amir al-Mu’minin (a.s.), explained and then asked, ‘Bring two bowls of water. I will show the difference between the liver and spleen.’ Two bowls of water were brought and he (the Imam) said, ‘Cut the middle of the liver and cut the middle of the spleen. He (the Imam) then commanded to rub them in the water. After being rubbed in water the liver turned (a little) white but it remained the same and nothing was reduced thereof. The spleen in this process did not turn white but all of its contents came out and turned into blood, all that was left was its skin and its vein. He (the Imam) said, ‘This is the difference between the two. This is flesh and this is blood.’”
