Treatment with the Gall of the Vulture

Question:
Your Eminence the Shaykh, may Allah grant you success, some people use the gall of the vulture in treating asthma, and it has been established with some of them that it is beneficial, and some have been cured by the permission of Allah. Is that permissible?

Answer:
No, it is not permissible to treat oneself with what is forbidden or with what is impure. The impure is forbidden. The Prophet (peace and blessings be upon him) said: In the lawful, one is free from the need for the forbidden. Even if they try it because it is beneficial, it exposes this benefit to opposition; the impurity opposes it, and the prohibition opposes it. In the forbidden, there may sometimes be things that have benefit, but if the harm is greater than the benefit, and the side of harm prevails, and it occurs, its benefit, or any thing that has benefit is called lawful, until one looks at this benefit: is it the stronger position or the weaker position?
If the benefit is the stronger position, it is lawful. If the opposite is the case and the harm is the stronger position, it is forbidden. Likewise, if the harm and the benefit are equal, it is also forbidden. So what remains for us is only if the benefit is the stronger position, in which case it is lawful.
