Is it permissible for a Muslim to speak the language of the non-Arabs (the gibberish of the non-Arabs)?

The Shaykh : 'Umar (may Allah be pleased with him) warned against the gibberish of the non-Arabs, saying, "Beware of it," and he also prohibited it. Thus, he combined warning and prohibition. By "non-Arabs" is meant anyone other than the Arabs, whether they are Persian, Roman, or further removed than that. It is not permissible for Muslims to adopt this language as their own. However, there is no harm in speaking some words or the like, or in using the names they use for things that come to us under those names, as was previously mentioned. Yes.
