(The Prophets 21:4)
God Almighty knows all things. The least little atom in the Heavens or on earth is not hidden from Him.
(City of Saba 34:3)
According to the Holy Quran (2:29-33), Adam was blessed with knowledge and was taught ‘all the Names’. This knowledge was not imparted to even the Angels:
30) Behold, thy Lord said to the angels: “I will create a vicegerent on earth.” They said: “Wilt Thou place therein one who will make mischief therein and shed blood? – whilst we do celebrate Thy praises and glorify Thy holy (name)?” He said: “I know what ye know not.”
31) And He taught Adam the nature of all things; then He placed them before the angels, and said: “Tell me the nature of these if ye are right.”
32) They said: “Glory to Thee, of knowledge We have none, save what Thou Hast taught us: In truth it is Thou Who art perfect in knowledge and wisdom.”
33) He said: “O Adam! Tell them their natures.” When he had told them, Allah said: “Did I not tell you that I know the secrets of heaven and earth, and I know what ye reveal and what ye conceal?”
(The Cow 2: 29-33)
There are many verses in the Holy Qur’an which speak of the various ways that God reveals Himself to His creation. These are called ayat (signs). Hence, the ayat of the Holy Qur’an speak to those whose hearts have been illuminated by the light of knowledge. The Holy Qur’an (42:51-52) states:
52) And thus have We, by Our Command, sent inspiration to thee: thou knewest not (before) what was Revelation, and what was Faith; but We have made the (Quran) a Light, wherewith We guide such of Our servants as We will; and verily thou dost guide (men) to the Straight Way.
Throughout the Holy Qur’an, God Almighty guides us to seek true knowledge beyond the limitations of our physical dimensions.
Molana Salaheddin Ali Nader Angha, the present Master of the M.T.O. Shahmaghsoudi® School of Sufism states: “Religion is about certainty, and certainty comes when it is grounded in knowledge that has been revealed to one by God, and no one else. Knowledge leads to certainty.”  Witnessing the truth brings certainty and peace to one’s life. In the School of Sufism, the focus is discovering the “Reality” of religion.
