Allah said,

﴿وَمَا يَنطِقُ عَنِ الْهَوَى ﴾

(Nor does he speak of desire), asserting that nothing the Prophet utters is of his own desire or wish,

﴿إِنْ هُوَ إِلاَّ وَحْىٌ يُوحَى ﴾

(It is only a revelation revealed.), means, he only conveys to the people what he was commanded to convey, in its entirety without additions or deletions. Imam Ahmad recorded that Abu Umamah said that he heard the Messenger of Allah say,

«لَيَدْخُلَنَّ الْجَنَّةَ بِشَفَاعَةِ رَجُلٍ لَيْسَ بِنَبِيَ مِثْلُ الْحَيَّيْنِ أَوْ مِثْلُ أَحَدِ الْحَيَّيْنِ رَبِيعَةَ وَمُضَر»

(Verily, numbers similar to the two tribes, or one of them, Rabi`ah and Mudar, will enter Paradise on account of the intercession of one man, who is not a Prophet.) A man asked, "O Allah's Messenger! Is not Rabi`ah a subtribe of Mudar.'' The Prophet said,

«إِنَّمَا أَقُولُ مَا أَقُول»

(I said what I said.) Imam Ahmad recorded that `Abdullah bin `Amr said, "I used to record everything I heard from the Messenger of Allah so it would be preserved. The Quraysh discouraged me from this, saying, `You record everything you hear from the Messenger of Allah , even though he is human and sometimes speaks when he is angry' I stopped recording the Hadiths for a while, but later mentioned what they said to the Messenger of Allah , who said,

«اكْتُبْ، فَوَ الَّذِي نَفْسِي بِيَدِهِ مَا خَرَجَ مِنِّي إِلَّا الْحَق»

(Write! By He in Whose Hand is my soul, every word that comes out of me is the Truth.)'' Abu Dawud also collected this Hadith.

﴿عَلَّمَهُ شَدِيدُ الْقُوَى - ذُو مِرَّةٍ فَاسْتَوَى - وَهُوَ بِالاٍّفُقِ الاٌّعْلَى - ثُمَّ دَنَا فَتَدَلَّى - فَكَانَ قَابَ قَوْسَيْنِ أَوْ أَدْنَى - فَأَوْحَى إِلَى عَبْدِهِ مَآ أَوْحَى - مَا كَذَبَ الْفُؤَادُ مَا رَأَى - أَفَتُمَـرُونَهُ عَلَى مَا يَرَى - وَلَقَدْ رَءَاهُ نَزْلَةً أُخْرَى - عِندَ سِدْرَةِ الْمُنتَهَى - عِندَهَا جَنَّةُ الْمَأْوَى - إِذْ يَغْشَى السِّدْرَةَ مَا يَغْشَى - مَا زَاغَ الْبَصَرُ وَمَا طَغَى - لَقَدْ رَأَى مِنْ ءَايَـتِ رَبِّهِ الْكُبْرَى ﴾

(5. He has been taught by one mighty in power.) (6. Dhu Mirrah then he Istawa.) (7. While he was in the highest part of the horizon,) (8. Then he approached and came closer,) (9. And was at a distance of two bows' length or less.) (10. So (Allah) revealed to His servant whatever He revealed.) (11. The heart lied not in what he saw.) (12. Will you then dispute with him about what he saw) (13. And indeed he saw him at a second descent.) (14. Near Sidrat Al-Muntaha.) (15. Near it is the Paradise of Abode.) (16. When that covered the lote tree which did cover it!) (17. The sight turned not aside, nor it transgressed beyond the limit.) (18. Indeed he saw of the greatest Ssgns of his Lord.)
