I’ve got two questions. Firstly, I would like to know, when you read namaz, if somebody comes in front of you, why is that bad? Because he interrupts your concentration. If people are permitted to pass along to and fro and you are saying your prayer and you want to bow down, it will be all chaos and all the time your concentration will be diversified and shattered into pieces.
So, to maintain your concentration so that you are not disturbed, the Holy Prophet told us that when somebody is saying prayer, it is better to wait for years rather than to cross his path and to disturb him.
