Ruling on Delaying Prayer for One Entrusted with a Trust or Guard Duty

Question:
I work as an employee at the Saudi Telephone Company, and the responsible supervisor prevents me from performing the prayer during working hours, even though the mosque is opposite the telephone building. What is your opinion on this?

Answer:
It is obligatory for you to pray in your place, because you are like a guard. A guard who is guarding money, a farm, or something else prays in his place, and congregation is not obligatory for him if going to the congregation would cause him to neglect the guard duty. Perhaps something may come over the telephone that requires caution. The result is that the one entrusted with the important telephone for Muslims is like a guard who prays at the place of the guard duty.
As for wasting time, no, he must pray within the time. Even if it is estimated that the telephone will ring, the duration of the prayer is short, five minutes or less.
So it is obligatory to pray the prayer within its time, and it is not permissible to neglect it for the sake of the guard duty, nor for the sake of the telephone.
If there is a dire necessity, then taking turns is obligatory. This guard is to take turns for some of the time, then he goes and prays, and the other guard, who has already prayed, takes his place.
As for being entrusted with a guard duty that prevents him from praying, this is injustice, and it is not permissible.
