Article 163
Individuals are prevented from possessing laboratories producing materials that could harm the *Ummah* or the State, or materials that the *Shari’ah* forbade.
Its evidence is the *Shari’ah* principle:
(الشيء المباح إذا كان فرد من أفراده يؤدي إلى ضرر يمنع ذلك الفرد ويبقى الشيء مباحاً)
*“If one item of a permitted thing leads to a harm, only that one is prohibited, and the thing remains permitted”*, and laboratories whose private ownership leads to harm are prevented from being privately owned, such as nuclear laboratories and anything else whose private ownership would lead to harm.
