Surah Ad-Dukhan, Ayah 10

Alarming the Idolators with News of the Day when the Sky will bring forth a visible Smoke

Allah says, these idolaters are playing about in doubt, i.e., the certain truth has come to them, but they doubt it and do not believe in it. Then Allah says, warning and threatening them:

فَارْتَقِبْ يَوْمَ تَأْتِى السَّمَآءُ بِدُخَانٍ مُّبِينٍ

(Then wait you for the Day when the sky will bring forth a visible smoke.) It was narrated that Masruq said, "We entered the Masjid -- i.e., the Masjid of Kufah at the gates of Kindah -- and a man was reciting to his companions,

يَوْمَ تَأْتِى السَّمَآءُ بِدُخَانٍ مُّبِينٍ

(the Day when the sky will bring forth a visible smoke.) He asked them; `Do you know what that is' That is the smoke that will come on the Day of Resurrection. It will take away the hearing and sight of the hypocrites, but for the believers it will be like having a cold."' He said, "We came to Ibn Mas`ud, may Allah be pleased with him, and told him about that. He was lying down, and he sat up with a start and said, `Allah said to your Prophet

لَيْلَةٍ مُّبَارَ‌كَةٍ 'blessed night', in verse 2 according to majority of the Commentators, refers to 'laylatul Qadr' or the 'Night of Power' which occurs in the last ten nights of the month of Ramadan. During this night Allah sends down countless blessings for his slaves/servants. It has been explicitly mentioned in Surah Al-Qadr, thus:

إِنَّا أَنزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ‌

"We sent it (the Qur'an) down in the Night of Qadr". (97:1)

This clearly indicates that the phrase 'laylah mubarakah' (blessed night) occurring in the verse refers to the 'Night of Power'. It is narrated in a Tradition of the Prophet ﷺ that all Prophets (علیہم السلام) since the inception of man till the end, received their respective Books in the month of Ramadan on different dates. Sayyidna Qatadah ؓ reports on the authority of Sayyidna Wathilah ؓ that the Messenger of Allah ﷺ said that Prophet Ibrahim (علیہ السلام) received his Scriptures on 1st Ramadan, Torah was revealed on 6th Ramadan, Zabur was revealed on 12th Ramadan, Injil was revealed on 18th Ramadan and the Holy Qur'an was revealed on the night of 24th, that is, on 25th Ramadan. (Qurtubi).

The total clarity of the Quran is in itself proof of its being the Book of God, and this being so, its tidings and forecasts are also definitive. There is no scope for any doubt about them. The beginning of the revelation of the Quran took place on a particular night—a night fixed for important godly decisions. The revelation of the Quran was not a simple event. It resulted from a decision regarding the dawn of a new era of history. That is why it was revealed on this specially blessed night. Primarily, the Quran was and still is a declaration of Truth. It came into existence in order to show the falsity of polytheism and the truth of the Unity of God. Most importantly, it provides man with a standard by which to distinguish between truth and falsehood. The Quran was the distinguisher among nations solely on this basis.
