What is the ruling on performing Friday Prayer at the workplace in Sweden, given that there is no sermon and only two rak'ahs are prayed in congregation, and is the presence of an imam a condition, knowing that it is difficult to leave work to go to the mosque?

Your brother is not permitted to perform the Friday prayer at his workplace. Rather, he must strive to go to the nearest mosque where the Friday prayer is established. Missing the Friday prayer without a legitimate Shar'i excuse is considered a major sin. Work is not considered an excuse for missing it except in cases of extreme necessity where there is a fear of losing one's job, and there is no alternative, and one does not possess enough for sustenance. In this case, he may perform the Friday prayer at his workplace if there is a sufficient number of residents (those who consider that city their home) with him, and a sermon must be delivered. If the required number is not available, then he must pray Dhuhr four rak'ahs and endeavor to replace his job with another that does not prevent him from performing the prayer. As for the nisab (definition) (threshold) for Zakat (definition) on Euros, it is the equivalent value of 85 grams of gold or 595 grams of silver, and 2.5% of the money must be given if it reaches the nisab.
