Allah tells us that He revealed the Magnificent Qur'an on a blessed night, 
Laylatul-Qadr (the Night of Decree), as He says elsewhere:
[إِنَّا أَنزَلْنَـهُ 
فِى لَيْلَةِ الْقَدْرِ ]
(Verily, We have sent it down in the Night of Al-Qadr) (97:1). This was in 
the month of Ramadan, as Allah tells us:
[شَهْرُ رَمَضَانَ 
الَّذِى أُنزِلَ فِيهِ الْقُرْآنُ]
(The month of Ramadan in which was revealed the Qur'an) (2:185). We have 
already quoted the relevant Hadiths in (the Tafsir of) Surat Al-Baqarah, and 
there is no need to repeat them here.
[إِنَّا كُنَّا 
مُنذِرِينَ]
(Verily, We are ever warning.) means, telling them what is good for them and 
what is harmful for them, according to Shari`ah, so that the proof of Allah may 
be established against His servants.
[فِيهَا يُفْرَقُ 
كُلُّ أَمْرٍ حَكِيمٍ ]
(Therein (that night) is decreed every matter, Hakim.) means, on 
Laylatul-Qadr, the decrees are transferred from Al-Lawh Al-Mahfuz to the 
(angelic) scribes who write down the decrees of the (coming) year including life 
span, provision, and what will happen until the end of the year. This was 
narrated from Ibn `Umar, Mujahid, Abu Malik, Ad-Dahhak and others among the 
Salaf.
[حَكِيمٌ]
(Hakim) means decided or confirmed, which cannot be changed or altered. Allah 
says:
[أَمْراً مِّنْ 
عِنْدِنَآ]
(As a command from Us.) meaning, everything that happens and is decreed by 
Allah and the revelation that He sends down -- it all happens by His command, by 
His leave and with His knowledge.
[إِنَّا كُنَّا 
مُرْسِلِينَ]
(Verily, We are ever sending,) means, to mankind, sending Messenger who will 
recite to them the clear signs of Allah. The need for this was urgent.
[رَحْمَةً مِّن 
رَّبِّكَ إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ رَّبُّ السَّمَـوَتِ وَالاٌّرْضِ 
وَمَا بَيْنَهُمَا]
((As) a mercy from your Lord. Verily, He is the All-Hearer, the All-Knower. 
The Lord of the heavens and the earth and all that is between them,) means, the 
One Who sent down the Qur'an is the Lord, Creator and Sovereign of the heavens 
and the earth and everything in between them.
[إِن كُنتُمْ 
مُّوقِنِينَ]
(if you (but) have a faith with certainty.) Then Allah says:
[لاَ إِلَـهَ إِلاَّ 
هُوَ يُحْىِ وَيُمِيتُ رَبُّكُمْ وَرَبُّ ءَابَآئِكُمُ الاٌّوَّلِينَ ]
(La ilaha illa Huwa. He gives life and causes death -- your Lord and the Lord 
of your forefathers.) This is like the Ayah:
[قُلْ يَأَيُّهَا 
النَّاسُ إِنِّى رَسُولُ اللَّهِ إِلَيْكُمْ جَمِيعًا الَّذِى لَهُ مُلْكُ 
السَّمَـوَتِ وَالاٌّرْضِ لا إِلَـهَ إِلاَّ هُوَ يُحْىِ وَيُمِيتُ]
(Say: "O mankind! Verily, I am sent to you all as the Messenger of Allah -- 
to Whom belongs the dominion of the heavens and the earth. La ilaha illa Huwa. 
He gives life and causes death...) (7:158)
[بَلْ هُمْ فِى شَكٍّ 
يَلْعَبُونَ - فَارْتَقِبْ يَوْمَ تَأْتِى السَّمَآءُ بِدُخَانٍ مُّبِينٍ - يَغْشَى 
النَّاسَ هَـذَا عَذَابٌ أَلِيمٌ - رَّبَّنَا اكْشِفْ عَنَّا الْعَذَابَ إِنَّا 
مْؤْمِنُونَ - أَنَّى لَهُمُ الذِّكْرَى وَقَدْ جَآءَهُمْ رَسُولٌ مُّبِينٌ - ثُمَّ 
تَوَلَّوْاْ عَنْهُ وَقَالُواْ مُعَلَّمٌ مَّجْنُونٌ - إِنَّا كَاشِفُواْ 
الْعَذَابِ قَلِيلاً إِنَّكُمْ عَآئِدُونَ - يَوْمَ نَبْطِشُ الْبَطْشَةَ 
الْكُبْرَى إِنَّا مُنتَقِمُونَ ]
(9. Nay! They play about in doubt.) (10. Then wait you for the Day when the 
sky will bring forth a visible smoke,) (11. Covering mankind, this is a painful 
torment.) (12. (They will say): "Our Lord! Remove the torment from us, really we 
shall become believers!'') (13. How can there be for them an admonition, when a 
Messenger explaining things clearly has already come to them.) (14. Then they 
had turned away from him and said: "(He is) one taught, a madman!'') (15. 
Verily, We shall remove the torment for a while. Verily, you will revert.) (16. 
On the Day when We shall strike you with the great Batshah. Verily, We will 
exact retribution.)
