Contemplation and thinking— tafakkukr—is the source of Islamic spirituality. Contemplative spirituality is received through a thinking process rather than the cessation of intellectual activity. The Quran attaches great importance to reflection and serious thought. As mentioned in the Quran, the process of contemplation, tafakkur, is the beginning of the spiritual activity. Several verses in the Quran indicate that innumerable signs of God are extant in the heavens and the earth. The observance of God’s signs is the most significant source of spirituality. Man can discover God by pondering upon and contemplating His signs spread throughout His creation. Man can learn lessons from these signs to start living a God-oriented life. The concept of spirituality in Islam is based on the principle of God-Realisation. God is the treasure house of all virtues. Moreover, when man’s contact with God is established at the psychological level, an unseen, inner revolution is brought about within a person, called spirituality. As the Quran tells us, “Prostrate yourself and draw near.” (96: 19). God is always close to us—closer than the jugular vein (50: 16). By total surrender to God, the soul can attain nearness to God. When man engages himself in proper devotion, he comes close to God. Through an invisible cord, he comes in contact with God. His entire existence comes to be pervaded by this indescribable feeling, which is called spiritual experience. This has been termed Rabbaniat in the Quran (Be people of the Lord.) (3: 79). Rabbani means one whose thinking, the focus of life, and actions are God-oriented. When an individual attains spirituality, he appears to live in this world, but he has found another far superior world. Everything in the universe seems to convey to him a divine message. Due to his high state of receptivity, he reaches the stage where the wavelength of God and man become one. Moreover, he is enabled, in the words of the Prophet: “to see with God’s eye, to speak with God’s tongue, to walk with God’s foot, to hear with the ear of God.”
