From an educational perspective, is it better to enroll one's son in a model Azhari institute or in a language school, taking into consideration the parents' objection due to the father being well-off?

The Prophet, peace and blessings be upon him, his Companions, and the Successors did not learn languages other than Arabic except out of necessity, as the Prophet, peace and blessings be upon him, did when he learned Syriac due to his need to translate books. This indicates the permissibility of learning foreign languages out of necessity, such as for ambassadors, and it may be a collective obligation (fard kifaya). However, today, many Muslims learn these languages for boasting and showing off, which has led to the weakening of the Arabic language among them. Muslims today are in dire need of learning the religious sciences because it is an obligation upon every Muslim. Caution must be exercised against eagerly enrolling in foreign schools because they destroy the language of the Qur’an, and because those in charge of them are generally non-Muslims.
