Tafsir

In the cited verses, the Mushriks had demanded the kind of miracles they chose. Verses that follow tell them that they already have a miracle, the miracle of the Qur'an shown at the hands of the Holy Prophet ﷺ before them, a miracle even they could not deny. Now if they were demanding these miracles honestly, only to determine the veracity of the messenger of Allah, then, their demand stands accepted (and the miracle is on). And if this demand is simply to gratify their hostility, the showing of miracles demanded by them would remain redundant, for who could expect from such hostile people that they would embrace Islam, even after having seen those miracles. So, the essential point is that the Holy Qur'an is a clear miracle that cannot be denied.

A refutation of the false doubts engineered by Mushriks and Kafirs in it has been made in the next two verses (13, 14): These people say that the Prophet of Islam has himself made up the Qur'an - it is no book of Allah.

In answer, it was said: If you really think so, that Muhammad ﷺ can make a Qur'an like this, all by himself, then, you too, better come up with only ten Surahs like that. And it is not necessary either that these ten Surahs have to be made by any one person. Instead, let everyone in the world join forces and come up with it. And when they fail to make even ten Surahs, then, the Holy Prophet ﷺ was to tell them: Now the reality stands out loud and clear, for had this Qur'an been the word of some human being, other human beings could have also been able to make something like this. And that they all fail to do so is a strong proof of the fact that this Qur'an has been revealed only with the knowledge of Allah in which there is no room for the least increase or decrease and that it is beyond human power.

At this place, the Holy Qur'an has said that they should come up with ten Surahs like it. And in another verse it was also said: ` Then, bring a Sarah the like of this - al-Baqarah, 2:23.'
