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:

"Does man think that he will be left Sudaa1 (without a purpose)?" (Qur'an 75: 36)
One of Allah's ways of guidance is the office of Messengership which involves the
Message and the Messenger. The essence of the Message is to direct man to relate to
His Creator through complete submission and obedience (this is the meaning of
Islam).
Man does not possess the air he breathes. He does not create. He is not the creator of
himself. 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. That is why
Allah called the Message of Islam, an Inspiration and a Light:
 
"And thus We have sent to you (O Muhammad) Ruhan2 of Our command. You
knew not what is the Book (the Qur'an), nor what is Iman (Faith)? But We have
made it (the Qur'an) a Light, whereby We guide whom We will of Our
bondsmen. And verily you are indeed guiding (mankind) to the Straight Path."
(Qur'an 42: 52)
The Inspiration brings Life, and the Light brings Light. Allah gave a beautiful parable
on the Message and its effects, saying:

He sends down water (rain) from the sky, and the valleys flow according to their
measure, but the flood bears away the foam that mounts up to the surface, and
(also) from that (ore) which they heat in the fire in order to make ornaments or
utensils, rises a foam like unto it, thus does Allah (by parables) show forth truth
and falsehood. Then, as for the foam it passes away as scum upon the banks,

1Sudaa, has many meanings including, aimless, without a purpose, not to be held accountable, neglected etc.
2Ruhan, an inspiration and a mercy.3

while that which is for the good of mankind remains in the earth. Thus Allah set
forth parables (for the Truth and Falsehood, i.e. Belief and Disbelief)." (Qur'an
13: 17)

 Dr. Saleh AsSaleh shows in his introduction to this book that Allah could not have created this universe without a purpose. He is AllWise, All Knowledgeable, AllMerciful and AllJust. 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.
