In Musnad Al-Bazzar, it is recorded from Abu At-Tufayl `Amir bin Wathilah from Zayd bin Harithah that the Messenger of Allah said to Ibn Sayyad:

«إِنِّي قَدْ خَبَأْتُ خَبْأً فَمَا هُوَ؟»

(I am concealing something, what is it) And the Messenger of Allah was concealing Surat Ad-Dukhan from him. He (Ibn Sayyad) said: "It is Ad-Dukh.'' The Messenger of Allah said,

«اخْسَأْ مَا شَاءَ اللهُ (كَانَ)»

(Be off with you! Whatever Allah wills happens.)

[بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ ]

In the Name of Allah, the Most Gracious, the Most Merciful.

[حم- وَالْكِتَـبِ الْمُبِينِ- إِنَّآ أَنزَلْنَـهُ فِى لَيْلَةٍ مُّبَـرَكَةٍ إِنَّا كُنَّا مُنذِرِينَ- فِيهَا يُفْرَقُ كُلُّ أَمْرٍ حَكِيمٍ- أَمْراً مّنْ عِنْدِنَآ إِنَّا كُنَّا مُرْسِلِينَ- رَحْمَةً مّن رَّبّكَ إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ- رَبِ السَّمَـوتِ وَالاْرْضِ وَمَا بَيْنَهُمَآ إِن كُنتُم مُّوقِنِينَ- لاَ إِلَـهَ إِلاَّ هُوَ يُحْىِ وَيُمِيتُ رَبُّكُمْ وَرَبُّ ءابَآئِكُمُ الاْوَّلِينَ-]

(1. Ha Mim.) (2. By the manifest Book that makes things clear.) (3. We sent it down on a blessed night. Verily, We are ever warning.) (4. Therein (that night) is decreed every matter, Hakim.) (5. As a command from Us. Verily, We are ever sending,) (6. (As) a mercy from your Lord. Verily, He is the All-Hearer, the All-Knower.) (7. The Lord of the heavens and the earth and all that is between them, if you (but) have a faith with certainty.) (8. La ilaha illa Huwa. He gives life and causes death -- your Lord and the Lord of your forefathers.)
