Surah 17. Al-Israa
Ayah 105 - 109
105 وَبِٱلْحَقِّ أَنزَلْنَـٰهُ وَبِٱلْحَقِّ نَزَلَ ۗ وَمَآ أَرْسَلْنَـٰكَ إِلَّا مُبَشِّرًا وَنَذِيرًا
106 وَقُرْءَانًا فَرَقْنَـٰهُ لِتَقْرَأَهُۥ عَلَى ٱلنَّاسِ عَلَىٰ مُكْثٍ وَنَزَّلْنَـٰهُ تَنزِيلًا
107 قُلْ ءَامِنُوا۟ بِهِۦٓ أَوْ لَا تُؤْمِنُوٓا۟ ۚ إِنَّ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ مِن قَبْلِهِۦٓ إِذَا يُتْلَىٰ عَلَيْهِمْ يَخِرُّونَ لِلْأَذْقَانِ سُجَّدًا
108 وَيَقُولُونَ سُبْحَـٰنَ رَبِّنَآ إِن كَانَ وَعْدُ رَبِّنَا لَمَفْعُولًا
109 وَيَخِرُّونَ لِلْأَذْقَانِ يَبْكُونَ وَيَزِيدُهُمْ خُشُوعًا ۩
[105-109] We have sent down the Qur'an with the truth and with the truth it has come down; and O Muhammad, We have sent you only to give good news (to the Believers) and warning (to the disbelievers).118 And we have sent down this Qur'an piecemeal so that you may recite it to the people gradually piece by piece, and We have sent it down by gradual Revelations119 (to suit particular occasions).O Muhammad, say to these people, “Whether you believe in it or not, those who were given the knowledge before this,120 fall prostrate on their faces when it is recited to them and cry out, “Our lord is glorious and His promise was surely to be fulfilled.” And they fall down on their faces, weeping when they listen to it, and this increases their Humility121 all the more.122
118That is, "It is not your responsibility to cause, in a supernatural manner, springs to gush forth or gardens to grow or pieces of the sky to fall down in order to convince those people who do not fudge the Qur'an by its teachings nor decide between the Truth and falsehood on merit. As the Qur'an has been sent down with truth, you should present it before the people and tell them plainly that the one, who believes, does so for his own good and the one who rejects it, does it at his own peril."
119This is an answer to this objection: "Why has not Allah sent down His Message as a whole? Why is He sending it piecemeal? Has Allah any need to think deliberately what to send down?" As the answer to this objection has been given in XVI: 101-102 and in the Explanatory Notes 104-106 added to them, there is no need to repeat the same here.
120This refers to those people of the Book who were well-versed in the Scriptures and could judge them from their themes and wording.
121That is, "When they listen to the Qur'an, they at once recognize that its bearer is the promised Prophet mentioned in the Books of the former Prophets."
122This attitude of the righteous people of the Book has been mentioned at several places in the Qur'an, e.g., III: 113-114, 199, V: 83-84.
