Is it permissible to pray in a ritually impure garment for someone who is unable to change their clothes due to work circumstances?

It is not permissible for a Muslim to pray in a ritually impure garment. One must take measures that facilitate performing the prayer in the prescribed manner, such as preparing a special garment for prayer, or wearing two garments and removing the impure one when intending to pray. If this is absolutely impossible, then one must pray at the appointed time in their current state.
