Combining Salahs for employees away from their place of residence when there is little rain

Q 1: Here in Al-Bahah, it sometimes rains a lot in spring and sometimes little. Sometimes it rains in the time of the Zhuhr (Noon) Prayer while we are at work. The places where the workers actually work vary in distance from the workplace from one worker to another, up to around 50 km. Some of the workers want to perform the Salah (Prayers) in the workplace Masjid (mosque), combining the Zhuhr and ‘Asr (Afternoon) Prayers. My question is: Is this permissible for us to combine Salahs under these conditions or not? Some of the workers are far from the city, as I mentioned, and if they come from their work and the time for the ‘Asr Prayer comes, it might be raining. Please advise us on this matter.

A: It is not permissible for you to combine the Salahs under these circumstances, because there is no good reason. It is Wajib (obligatory) upon you to perform the Zhuhr and ‘Asr Prayers in their respective prescribed times. Allah (Exalted be He) says: Verily, As-Salât (the prayer) is enjoined on the believers at fixed hours. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
