Is proficiency in the Arabic language obligatory for a writer, especially in religious articles, and must articles be reviewed to ensure their linguistic and grammatical soundness before publication?

It is incumbent upon anyone who writes in religious fields to be proficient in the Arabic language in order to formulate their message correctly, so that their article is sound in structure and meaning. Otherwise, their advice will be distorted. Learning Arabic is a communal obligation (fard kifaya), but for individuals, it is obligatory to learn the necessary amount to perform their religious duties. The phrase "عديد الناس" (many people) is imprecise; the more eloquent phrase is "العديد من الناس" (a lot of people) to indicate multitude, or "عديد الناس" if you mean countless multitude. The correct writing is "تتعلق بالجانب الديني" (related to the religious aspect) and "الاهتمام بإخراج" (attention to producing/directing).
