In the Name of Allah Most Gracious Most Merciful.Allah Subhanahu wa ta'ala is the Most Merciful and the Most Gracious. He loves His creatures and servants much much more than a mother loves her child. So how can He leave us unguided, unprotected and unrewarded? He has given us intelligence above all His Creations in the world.
By using our intelligence, insight and understanding we can easily see the signs of Allah which are so prominent and so numerous! Our own self is a sign of Allah and all that is around us from plants to animals and from the skies to our earth!
It is entirely our fault if we do not want to direct our intelligence to the right direction or way to understand Allah and His Greatness.
Not only this, Allah has not left His creation without any help or guidance; it is always present near us so that we can refer to it anytime!
That guidance is the Holy Quran, the Pure and True message of Allah is with us to guide us to the Right Path.
This Light of Guidance is always shining in the world so that anybody who wants can seek guidance, help or enlightenment from it till the Last Hour is established.
It is always alive in the hearts of all Muslims who love Allah, His Messenger and have faith in all that Allah sent through His Messengers (May Peace and Blessings of Allah be upon them all).
So, first it was Human Intelligence that was bestowed to help man understand his existence and end and then he was provided with an everlasting guide in the form of the Quran.
But this is not the end.
Apart from this Allah has given us the Life of our Beloved Prophet Mohammed (May Peace and Blessings of Allah be upon him) to see how a Muslim should live.
He chose His Messenger from among the common people, who had a simple life so that everyone could identify and relate to him easily.
