The questioner : The questioner asks: What is the ruling on using a drug that contains a narcotic substance? What is the ruling on prescribing it to a patient if I work as a doctor?

The questioner : And what is the ruling on prescribing it to a patient if I work as a doctor?

The Shaykh : I was.

The questioner : I work the road.

The Shaykh : If the drug containing anesthesia is necessary, there is no harm in it. Does anesthesia contain a narcotic or not? It contains a narcotic, and there is no harm in it. You must know the difference between intoxication and anesthesia. Intoxication is the loss of reason, but for the sake of pleasure and delight. So the intoxicated person—may Allah keep us safe—his reason is gone, but he is like a madman, not like the anesthetized person. The anesthetized person loses sensation and touch and the like, but the madman does not lose this; rather, he loses his conduct. The intoxicated person does not lose that, but he loses his conduct just as the madman loses his conduct. Then he also feels that he is above people, as the pre-Islamic poet said, “We drink it, and it leaves us as kings,” and…
Look at the story of Hamzah ibn 'Abd al-Muttalib (may Allah be pleased with him), the master of the martyrs. When a camel belonging to 'Ali ibn Abi Talib (may Allah be pleased with him) passed by him, Hamzah was drunk. He was drunk, and a slave girl in his house was singing to him, saying, "Oh Hamzah, for the noble poetry." She was inciting him to slaughter these camels, to slaughter the two camels and eat them. So he stood up, took a spear, and gored their bellies to eat them while he was drunk. Then 'Ali ibn Abi Talib (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) to intercede for his uncle. The Prophet (peace and blessings be upon him) came to Hamzah to speak to him and found that he had not yet sobered up. So Hamzah kept saying to the Messenger (peace and blessings be upon him)—Hamzah was saying to the Messenger, "May Allah send blessings and peace upon him"—"Are you not the slaves of my father?" Meaning, how can you speak about 'Ali when you are among the slaves of my father? He said this to the Messenger (peace and blessings be upon him). This is a word of disbelief, but the man was drunk. The Prophet (peace and blessings be upon him) returned and left him. Now, being drunk means that it equates a person to insanity.
And this story was before the prohibition of intoxicants, because I think each of you has a sense of honor in his chest: how could Hamzah ibn 'Abd al-Muttalib drink intoxicants? This was before the prohibition of intoxicants, because Hamzah ibn 'Abd al-Muttalib, the master of the martyrs, was killed as a martyr in the fourth year of the Hijrah. I say four; am I wrong or not wrong? In the third year of the Hijrah, when? In the Battle of Uhud. He was killed as a martyr in the Battle of Uhud, and the prohibition of intoxicants was after that, either in the fifth or sixth year of the Hijrah. And it is known that if something is lawful, there is no harm in a person consuming it.
In any case, I gave you this example to make it clear that intoxication is not anesthesia. If there is a benefit for the patient in anesthesia, there is no harm in it, and there is no harm in a doctor prescribing it to the patient.
