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.)
