The Quran was the proof leading to God and delivered to prophet Mohamed peace be as well as a miracle; a linguistic miracle to defy the fluent poets of his time. No one could or can deliver anything similar to the Quran to be followed as mentioned in the following verses.

39:28 Az-Zumar

قُرْآنًا عَرَبِيًّا غَيْرَ ذِي عِوَجٍ لَعَلَّهُمْ يَتَّقُونَ

[It is] an Arabic Qur'an, without any deviance that they might become righteous.

17:88 Al-Israa

‎قُلْ لَئِنِ اجْتَمَعَتِ الْإِنْسُ وَالْجِنُّ عَلَىٰ أَنْ يَأْتُوا بِمِثْلِ هَٰذَا الْقُرْآنِ لَا يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا

Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants."

17:89 Al-Israa

‎وَلَقَدْ صَرَّفْنَا لِلنَّاسِ فِي هَٰذَا الْقُرْآنِ مِنْ كُلِّ مَثَلٍ فَأَبَىٰ أَكْثَرُ النَّاسِ إِلَّا كُفُورًا

And We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief.

11:13 Hud

أَمْ يَقُولُونَ افْتَرَاهُ ۖ قُلْ فَأْتُوا بِعَشْرِ سُوَرٍ مِثْلِهِ مُفْتَرَيَاتٍ وَادْعُوا مَنِ اسْتَطَعْتُمْ مِنْ دُونِ اللَّهِ إِنْ كُنْتُمْ صَادِقِينَ

Or do they say, "He invented it"? Say, "Then bring ten surahs like it that have been invented and call upon [for assistance] whomever you can besides Allah, if you should be truthful."

11:14 Hud

فَإِلَّمْ يَسْتَجِيبُوا لَكُمْ فَاعْلَمُوا أَنَّمَا أُنْزِلَ بِعِلْمِ اللَّهِ وَأَنْ لَا إِلَٰهَ إِلَّا هُوَ ۖ فَهَلْ أَنْتُمْ مُسْلِمُونَ

And if they do not respond to you - then know that the Qur'an was revealed with the knowledge of Allah and that there is no deity except Him. Then, would you [not] be Muslims?
