From Islamic point of view...
From Islamic point of view; emigration is not limited to the movement from a local position to a distant place. It rather includes all the useful changes from one state and situation to another. First of all the emigration must occur in our innerside, by which we must move from bad to good, and from wrong to right. We must keep away from evil company where we cannot put him down; but we then have to organize a position from which we may assault evil and its darkness.
[ 579 ] **THE COMMENTARY TRAVELLER'S PRAYERS (VERSE NO. 101)** Permission is given to Muslims to shorten their prayers when they are on journey. The practice of the prophet shows that; danger is not an essential condition for shortening the prayers during the journey. It might have been so in the first cases, because almost all the journeys of Muslims during the prophet's life time were full of danger!
Some commentators believe that the permission at first was due to fear and danger, and later it was extended and became a common instruction to cover all sorts of journeys with fear, or without. After all, the commandments about such prayers that are performed in fear and dangerous states, are issued through the next verse. Now almost all sects of Muslims shorten their prayers when they are on journey.
The apostle himself used to reduce the prayers of noon, after noon, and night, from their usual four units to only two units, when he was travelling. This is an order, and a favour of God to passengers on their journey.
