The people of the world are usually aware of two kinds of journey. One journey is that which is made to earn livelihood. The second one is that which is undertaken for pleasure and sight-seeing. In both [of] these journeys, a man is impelled to go abroad by his need and desire. He leaves home for a purpose of his own, he spends money or time for his own requirements, therefore, no question of sacrifice arises in such a journey. But the position of this particular journey which is called Hajj is quite different from that of other journeys.
