The pilgrimage has economic benefits for Muslims. They come from various walks of life; some are traders or industrialists, others are capitalists or farmers. They can discuss the financial problems of mutual benefit, the exchange of technical know-how or skills, or the exchange of goods and machinery between them.
Hajj is the fifth pillar of Islam and is an act of ibadah (worship), like prayer and fasting. It is a religious duty and is obligatory, once in their lifetime, for all those Muslims who can afford to perform it. All five pillars of Islam perform very important and specific functions in training a Muslim for the service of Islam.
This method of delivering the Message through the Prophet (or chosen man or Messenger) can be further illustrated as follows: The Boss of the company dictates his messages from time to time into a tape recorder. His secretary later transcribes the messages from the tape recorder into typewritten form, or types them on a stencil (master copy), and then produces as many copies as desired by cyclostyling or photocopying for distribution to the workers as circulars. A similar line of processes took place with the Qur’anic revelation.
