The speedy advance and promulgation of Islam were due to the sincere, indefatigable endeavours of our Holy Prophet more than anything else. In the propagation of Islam, the Holy Prophet utilized two powerful, effective forces: one, proficient speakers who had realized the truth and righteousness of Islam and who deeply loved and admired the Holy Prophet of Islam, and, two, the amazingly impressive letters, which revealed the vivifying precepts of Islam and which, in reality, were crystal clear reflections of Islam. He sent his messengers to different parts of the world although there were many hardships in their way and the needed means and facilities were scarce or unavailable. Now the holy soul of our Prophet is worried about Muslim societies, and no doubt he watches them to see how they attempt to promote Islam, to communicate the precepts of Islam to people all over the world, and also to see if they make use of modern technologies and media to propagate the holy teachings of Islam. So it is incumbent upon us to mobilize all our forces and powers to promote the cause of Islam and to spare no effort or self sacrifice in the propagation of this holy faith, so our eastern and western brothers and sisters in Islam may be led to this vivifying fountain of truth. It will be a great achievement for us to have the honour of such an invaluable service to Islam and to humanity in general. Just as our Holy Prophet said to 'Ali, 'I swear by God that if God leads a person towards salvation through you, it will be more valuable and beneficial to you than the value of all the beings in the whole world upon which the sun casts its rays'." 1
