Dr. Saleh As-Saleh shows in his introduction to this book that Allah could not have created this universe without a purpose. He is All-Wise, All- Knowledgeable, All-Merciful and All-Just. All of these attributes entail providing ways of guidance that would lead to the proper knowledge of Him, and thus the right way to worship Him. Allah sent his messengers to direct man to relate to His Creator through complete submission and obedience (this is the meaning of Islam). He needs to know what benefits him and what harms him. The Message from Allah comprehends everything. It brings man to live for a noble purpose. All forms of worship are explained in the Qur'an and by the Prophet. Worship is not left for our limited minds to decide upon their ways.

Islam consists of God’s guidance to humanity. It is not the religion of any particular people. It does not belong to any specific land. All Prophets of God, in all ages, and at all places, preached this very religion.
