If My servants ask you about Me, I am near . I answer the call of the caller when he calls upon Me. They should therefore respond to Me and believe in Me, so that hopefully they will be rightly guided. (Surat al-Baqara, 2:186)
Those who fail to appreciate Allah in the way He should be appreciated, as well as those who do not live according to the Qur'an, have vague and inadequate information about His existence. When asked, these people state that Allah created the heavens and Earth. Yet they assume that He is in the heavens and thus very far from them, although He forms and designs each person. The fact is, however, He introduces Himself to His servants through the verses sent from His Sight. He reveals just how close He is to His servants, as follows:
We created man and know what his own self whispers to him. We are nearer to him than his jugular vein. (Surat al-Qaf, 50:16)
When two people are talking, the third is Allah; when three people are talking, the fourth is Allah. If one whispers, Allah hears it; if one moves a little, Allah sees it. Allah, Who knows all of a person's thoughts, is with each person while he or she is sitting, walking, or speaking. While engaging in all of these, people cannot see Allah, but He sees them.
... So ask His forgiveness and then repent to Him. My Lord is Close and Quick to Respond. (Surah Hud, 11:61)Say: “If I am misguided, it is only to my detriment. But if I am guided, it is by what my Lord reveals to me. He is All-Hearing, Close-at-hand.” (Surah Saba, 34:50)
