There is a lengthy explanation to this, which follows a rugged road where many have slipped and gone astray; and beyond it is the secret of Destiny, which has always perplexed intelligent minds and into which the Master of Messengers has commanded us not to delve. So let the intelligent be content with hints and let it suffice them to believe that everything was created by Allah, and nothing exists without His will and power. Then let them require their selves to conform to the commandments and prohibitions, and take their Lord’s side against their selves in every circumstance.
A hadith says that is one of the treasures of the Garden.’ Understand the indication contained in terming it a ‘treasure’ and you will know that its meaning is among the mysteries; for reward is of the same species as the act. The Prophet s.a.w has also said ‘Two raka’ats in the depths of the night are one of the treasures of goodness.’ Their reward comprises a hidden treasure because the time of their occurence, namely the night implies this.
This can be clearly understood from the Prophet’s s.a.w saying: ‘When one believes in destiny, one’s sorrow departs.’ And in attributing ability and power to His Name, Allah, which is the axis of the Names and the most supreme of them, and in following it on most occasions with the two noble Names which indicate two of the attributes of the Holy Essence, namly those of Exaltation (Al-’Ali) and Magnitude (Al-’Azim), lies a sign that He totally transcends and is absolutely holier than the illusions of those who have strayed from the path, are blind to the evidence, and have delved without insight into the secret of destiny and the acts of Allah’s creatures. So take heed!
