What challenge has Allah made to those doubting that the Qur’an was revealed to the Messenger of Allah (peace be upon him)?
Allah has challenged them to produce the like of the Qur’an, or ten Surahs (chapters) of the Qur’an, or even just one Surah, but they failed. Allah (Exalted be He) says:
Say: "If the mankind and the jinn were together to produce the like of this Qur’ân, they could not produce the like thereof, even if they helped one another."
Or they say, "He (Prophet Muhammad صلى الله عليه و سلم) forged it (the Qur’an)." Say: "Bring you then ten forged Sûrahs (chapters) like unto it, and call whomsoever you can, other than Allâh (to your help), if you speak the truth!"
(Part No. 4; Page No. 13) And:
Or do they say: "He (Muhammad صلى الله عليه وسلم) has forged it?" Say: "Bring then a Sûrah (chapter) like unto it, and call upon whomsoever you can besides Allâh, if you are truthful!"
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
