So I swear by whatsoever you see, and by whatsoever you see not, that this is verily the word of an honored Messenger.meaning, Muhammad. Allah gave this description to him, a description which carries the meaning of conveying, because the duty of a messenger is to convey from the sender. Therefore, Allah gave this description to the angelic Messenger in Surah At-Takwir, where he said,إِنَّهُ لَقَوْلُ رَسُولٍ كَرِيمٍ ذِى قُوَّةٍ عِندَ ذِى الْعَرْشِ مَكِينٍ مُّطَـعٍ ثَمَّ أَمِينٍ Verily, this is the Word of (this Qur'an brought by) a most honorable messenger. Owner of power (and high rank) with Allah, the Lord of the Throne. Obeyed and trustworthy. (81:19-21)And here, it refers to Jibril.Then Allah says,وَمَا صَـحِبُكُمْ بِمَجْنُونٍ and your companion is not a madman. (81:22)meaning, Muhammad .وَلَقَدْ رَءَاهُ بِالاٍّفُقِ الْمُبِينِ And indeed he saw him in the clear horizon. (81:23)meaning, Muhammad saw Jibril in his true form in which Allah created him.وَمَا هُوَ عَلَى الْغَيْبِ بِضَنِينٍAnd he is not Danin with the Unseen. (81:24)meaning, suspicious.وَمَا هُوَ بِقَوْلِ شَيْطَـنٍ رَّجِيمٍ And it (the Qur'an) is not he word of the outcast Shaytan. (81:25)This is similar to what is being said here.وَمَا هُوَ بِقَوْلِ شَاعِرٍ قَلِيلً مَا تُوْمِنُونَ
