What is the ruling on renting the certificate of a pharmacist to open a pharmacy, given his permanent absence and the presence of his assistant, and is the money earned from this permissible?

It was previously explained that it is not permissible to hire a pharmacist's license to open a pharmacy. As for the money a Muslim receives from the state as a grant, it is not unlawful, even if the state deals in interest (riba). This is for two reasons: First, the state's financial resources are not entirely derived from interest and unlawful dealings; rather, a significant portion of them is from lawful sources. The proportion of interest and illicit gains in them is much less than the proportion of lawful gains. It is known that the Prophet, peace and blessings be upon him, used to deal with Jews and accept their gifts, even though they engaged in interest-based transactions. However, since their wealth was mixed with both lawful and unlawful elements, it was permissible to deal with them and accept their gifts. Second, according to the majority of scholars, with regard to interest and other illicit gains for which there is no known specific rightful owner, it is obligatory to spend them on the public interests of Muslims. Therefore, a grant that a Muslim receives from the state to learn a science that he needs or that Muslims need is permissible, because that is among the public interests of Muslims.
