Shift guards offering the Tarawih in congregation

Q 1: We are a group of police officers that work in Sabikhah police station. We are only four people in the shift. (Part No. 6; Page No. 91) We perform Tarawih (special supererogatory night Prayer in Ramadan) in a separate congregation at our place. Though we hear Salah (Prayer) held by neighboring Masjids (mosques) that are about 1500 meters far from our police station, we can not pray with them lest any car accident should happen and it is our job to deal with such matters. Is our Salah valid? Provide us with your beneficial answer please! May Allah reward you the best!

A: It is permissible that you perform Tarawih in a separate congregation at your work place as doing so enables you to combine between looking after your work and offering the concerned `Ibadah (worship).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
