A:
A man has to perform the five obligatory Prayers in congregation with the Muslims in the Masjid and it is not permissible for him to miss congregational Salah unless there is a legal excuse such as disease, fear or the like. The mentioned person has to assign clean clothes other than the work uniform in order to offer Salah, such a great act of worship, according to the Saying of the Prophet (peace be upon him):
"Whoever heard the call (adhan) and he did not come to it (the prayer), then there is no prayer for him except with an excuse”.
It was said to
Ibn `Abbas (may Allah be pleased with them), 'What is a legal excuse?' He said, 'Fear or disease'.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
