THE Quran refers to the Divine plan in these words (41: 53): We shall show them Our signs in the universe and within themselves, until it becomes clear to them that this is the Truth. Is it not enough that your Lord is the witness of all things?
The signs of God whose emergence was predicted in this verse of the Quran came into full expression in the 19th and 20th centuries. One aspect of the modern scientific revolution is that it has fully brought to life these signs of God. The modern scientific revolution has provided a commonly accepted intellectual ground between those who engage in dawah work (dayees or preachers) and their addressees (madus or addressees), through which dawah (missionary) work can be engaged in a more effective way.
