Surah 20. Ta-Ha
Ayah 133 - 135
133وَقَالُوا۟ لَوْلَا يَأْتِينَا بِـَٔايَةٍ مِّن رَّبِّهِۦٓ ۚ أَوَلَمْ تَأْتِهِم بَيِّنَةُ مَا فِى ٱلصُّحُفِ ٱلْأُولَىٰ
134وَلَوْ أَنَّآ أَهْلَكْنَـٰهُم بِعَذَابٍ مِّن قَبْلِهِۦ لَقَالُوا۟ رَبَّنَا لَوْلَآ أَرْسَلْتَ إِلَيْنَا رَسُولًا فَنَتَّبِعَ ءَايَـٰتِكَ مِن قَبْلِ أَن نَّذِلَّ وَنَخْزَىٰ
135قُلْ كُلٌّ مُّتَرَبِّصٌ فَتَرَبَّصُوا۟ ۖ فَسَتَعْلَمُونَ مَنْ أَصْحَـٰبُ ٱلصِّرَٰطِ ٱلسَّوِىِّ وَمَنِ ٱهْتَدَىٰ
[133-135] They say, "Why does he not bring us a Sign from his Lord?" Has not a clear Sign come to them containing all the teachings of the former Scriptures?116 Had We destroyed them with a scourge before its coming, these very people would have said, "Our Lord, why did you not send a Messenger to us so that we would have followed Your Revelations before we were humiliated and disgraced?" O. Muhammad say to them, "Everyone is waiting for the ultimate result;117 so you may also wait, for you will soon come to know who are following the straight path and who are rightly guided."
116This means that the Qur'an itself is a great miracle, for though it is being presented by an unlettered person from among them, it contains the essence of the teachings and guidance of all tire previous Divine Books. Not only this: it makes those teachings and guidance so plain and clear that even a simple man of the desert can benefit from them.
117That is, "Ever since the Message of Islam is being presented in your city (Makkah), it is not only every person of this city who is waiting for its ultimate result but also every one outside it, who has heard of it."
