“When My servants ask you about Me, [tell them that] I am indeed nearmost. I answer the supplicant‘s call when he calls Me. So let them respond to Me, and let them have faith in Me, so that they may fare rightly.” (The Qur‘an, 2:186) 

 One can only know God through God‘s own concept of Himself.  God may not be perceived by any of the five senses, nor can He be determined by scientific investigation.  God lies beyond man‘s scientific resources, because God, in fact, is the Creator of all things.  The believer is nevertheless in possession of the elements necessary for an awareness of God. 
With this, God is revealed in the contemplation of all that lies around us and within us. 
God has not abandoned humankind.  He has provided proof of his Existence and has indicated the way or the path leading to Him. 
Islam places considerable emphasis on the role of knowledge and right conduct, which should be perceived as the path to salvation, as well as a direct connection with God.  God is his only master and savior. 

The Prophet (PBD) said: 
"When God wants to answer or respond to His servant, He allows him to supplicate." 

"Ask God and ask Him in abundance, for verily there is nothing too great for Him." 

"Verily your Lord is bashful and kind. He would be too ashamed for His servant to open his hands to Him [in supplication] and for Him to return them empty."
