The impact of the Qur'an
It has been narrated that a major scholar of the past used to try to search any mistake in its language. His trials lasted for months and during this period, a group of men visited his house and ask him whether he had found anything yet. Finally, he shattered his inkpot and broke his pen and answered, “None can dispute that this is the Speech of Allah!” then he moved from the house and while passing by a mosque, he heard the voice of a young boy reciting the verse
وَقِيلَ يَا أَرْضُ ابْلَعِي مَاءكِ وَيَا سَمَاء أَقْلِعِي وَغِيضَ الْمَاء وَقُضِيَ الأَمْرُ وَاسْتَوَتْ عَلَى الْجُودِيِّ وَقِيلَ بُعْداً لِّلْقَوْمِ الظَّالِمِينَ
And it was said, “O earth, swallow your water, and O sky, withhold [your rain].” And the water subsided, and the matter was accomplished, and the ship came to rest on the [mountain of] Judiyy. And it was said, “Away with the wrongdoing people.” ( Surat Hood, verse 44) to which the man remarked, “It is not possible that a human could produce such words.”
The verse in question is one of the most beautiful, expressive, symbolic verses of the Qur’an, as the scholars of Arabic balaaghah (rhetoric) documented within it more than twenty-five different rhetorical devices within just 17 words. Similarly, many miracles of Quran are there that shows its authenticity. Moreover, there is an open challenge for everyone to bring a single ayat similar to Quran and in fact, you cannot.
