The Holy Quran 6:37 — Surah Al-An'am
Arabic text
وَقَالُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ءَايَةٌ مِّن رَّبِّهِۦ ۚ قُلْ إِنَّ ٱللَّهَ قَادِرٌ عَلَىٰٓ أَن يُنَزِّلَ ءَايَةً وَلَـٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ
Translation
They (the Kuffaar) say, "Why does a sign (miracle) not come to him (Rasulullaah) from his Rabb?" Say, "Verily Allaah is able to send a sign (at any time), but most of them do not know (that seeing a miracle is not always good because they will be almost immediately destroyed if they refuse to believe any miracle)."
Tafsir (excerpt) — Tafsir Usmani
that is, why was not some sign sent down from among those signs which they used to demand, as in the words of Almighty Allah: وَقَالُوْا لَنْ نُّؤْمِنَ لَكَ حَتّٰى تَفْجُرَ لَنَا مِنَ الْاَرْضِ يَنْۢبُوْعًا ۔ اَوْ تَكُوْنَ لَكَ جَنَّةٌ مِّنْ نَّخِيْلٍ وَّعِنَبٍ فَتُفَجِّرَ الْاَنْهٰرَ خِلٰلَهَا تَفْجِيْرًا ۔
