Prohibition of delaying the prayer after its prescribed time

 226. Abu Dhar narrated: The Messenger of Allah salla alayhi wa sallam said to me, ´´What would you do when you are under the rulers who delay the Salat (prayer) beyond its prescribed time, or they would make prayer a dead thing as far as its proper time is concerned?´´ I said, ´´What do you command me?´´ He said, ´´Perform prayer at its proper time, then catch it while they are performing it and join them, it would be a coluntary prayer for you.´´
