FIVE KEYS OF SECRET KNOWLEDGE, which are with God alone are said to be found in the last verse of Surah Luqman (xxxist, 34) of the Qur’an. “God! With Him is (1) the Knowledge of the Hour; (2) and He sendeth down rain; (3) and He knoweth what is in the wombs; (4) but no soul knoweth what shall be on the morrow; (5) neither knoweth any soul in what land he shall die. Verily God is knowing and is informed of all.”
