ترجمة الآية 3 من سورة Ad-Dukhan - English - سورة الدخان : عدد الآيات 59 - - الصفحة 496 - الجزء 25.
We sent it (this Quran) down on a blessed night [(i.e. night of Qadr, Surah No: 97) in the month of Ramadan,, the 9th month of the Islamic calendar]. Verily, We are ever warning [mankind that Our Torment will reach those who disbelieve in Our Oneness of Lordship and in Our Oneness of worship].
Indeed, We sent it down during a blessed night. Indeed, We were to warn [mankind].
(44:3) We revealed it on a Blessed Night, for We were intent on warning; *1
*1) The meaning of taking an oath by "the lucid Book" has been explained in E.N. 1 of Surah Zukhruf. Here also what has been sworn by is that Muhammad (upon whom be Allah's peace) is not the author of this Book but "We", and this Book by itself is enough to provide a proof of this. Furthermore, it has been said chat the night in which it was sent down was full of blessings. That is, the foolish and ignorant people, who have no idea of their own well-being or otherwise, regard the revelation of this Book as a disaster for themselves and are deeply anxious as how to get rid of it. But, as a matter of fact, the Hour when "We" decided to send down this Book to arouse the heedless, was highly blessed for them and _for aII mankind Some commentators have expressed the opinion that the meaning of sending down the Qur'an in that night is that its revelation began during that night, and some others think that the whole of the Qur'an was transferred from Umm alKitab and entrusted to the bearers of Revelation (angels), and then revealed to the Holy Prophet as and when required and demanded by the occasion and circumstances during 23 years. As to what actully happened Allah alone has the best knowledge. The night implies the same night which has been called lailat-ul-qadr in Surah Al-Qadr (97), There it has been said: `We sent it down in a Night of Glory," and here: `We sent it down in a blessed Night." Then the Qur'an itself has told that it was a night of the month of Ramadan (Al-Baqarah).
