The Interpretation of Sūrah Qadr.

The theme of Sūrah Qadr offers to acquaint the human being with the values, worth and importance of the Qur’an. Sūrah Qadr comes directly after Sūrah ʿAlaq in the arrangement of the Qur’an. The first five verses of Sūrah ‘Alaq refer to the initial revelation of the Holy Book; Sūrah Qadr, which follows, refers to the Qur’an again, indicating that it was revealed in a fateful night. It is a glorious Book and its revelation for mankind is full of blessings.
At the outset, Allah says: “We have sent it down.” That is, it is not a composition of Muḥammad (P.B.U.H. & H.H.) himself, but We Ourselves have revealed it.
Then, it is said that “We sent it down in the Night of Destiny.” Night of Destiny lies two meanings and both are implied here. First, that it is the night during which destinies are decided; or, in other words, it is not an ordinary night like the other nights, but a night in which destinies are made or marred. The revelation of this Book in this night is not merely the revelation of a book but an event which will change the destiny of not only the Quraish, or of Arabia, but of the entire world. The same thing has been said in Sūrah Dukhān. The other meaning is that this is, a night of unique honor, dignity and glory; so much so that it is better than a thousand months. Thus, the disbelievers of Mecca have been warned, as if to say: “You, on account of your ignorance regard this Book, which Muḥammad (P.B.U.H & H.H.) has presented, as a calamity for yourselves and complain that a disaster has befallen you; whereas the night in which it was decreed to be sent down was such a blessed night that a task was accomplished in it for the well being of mankind, which had never been accomplished even during a thousand months of history. This also has been said in verse 3 of Sūrah Dukhān in another way.
In conclusion, it has been stated that in this night the angels and Gabriel descend with every decree (which in verse 4 of Sūrah Dukhān has been described as arm-hakim: wise decree) by the leave of their Lord, and it is all peace from evening till morning; that is, there is no interference of evil in it, for all decrees of Allah are intended to promote good and not evil. So much so that even if a decision to destroy a nation is taken, it is taken for the sake of ultimate good, not evil.
