I asked Imam (as): "Why did Allah (swt) make wine, dead meat, blood, and the flesh of pigs forbidden?" Imam (as) replied: "Indeed, Allah (swt), Blessed and Exalted, did not forbid these things to His servants while permitting everything else out of mere preference for what He (swt) made lawful or out of disdain for what He (swt) forbade. Rather, Allah (swt) created the creatures and knew what sustains their bodies and what benefits them, so He (swt) made it lawful for them and permitted it. And He (swt) knew what harms them, so He (swt) prohibited it for them. However, He (swt) made it lawful for one in necessity during a time when his body cannot survive without it, and He (swt) commanded him to take from it only as much as is necessary, and no more." Then Imam (as) said: "As for carrion (dead meat), no one who consumes it experiences anything but a weakened body, diminished strength, and interrupted offspring. The one who eats carrion does not die except suddenly. As for blood, it causes the one who consumes it to develop jaundice, wild behavior, and hardness of the heart, along with a lack of compassion and mercy. Such a person cannot be trusted with his close ones or those who accompany him. As for flesh of pigs, Allah (swt), Blessed and Exalted, transformed some people into various forms, such as pigs, apes, and bears. Then He (swt) forbade the consumption of these deformed beings so that no benefit would be derived from them, and their punishment would not be taken lightly. As for wine, He (swt) forbade it due to its effects and its corruption." Then Imam (as) said: "Indeed, a habitual drinker of wine is like an idol worshipper. It causes trembling, destroys one's dignity, and drives one to commit forbidden acts, such as spilling blood and engaging in fornication. When intoxicated, he cannot be trusted even with his own household, as he loses his senses. Wine increases its drinker in nothing but evil."
