Sura al-Anʿām 6:124

وَإِذَا جَآءَتْهُمْ ءَايَةٌ قَالُوا۟ لَن نُّؤْمِنَ حَتَّىٰ نُؤْتَىٰ مِثْلَ مَآ أُوتِىَ رُسُلُ ٱللَّـهِ ٱللَّـهُ أَعْلَمُ حَيْثُ يَجْعَلُ رِسَالَتَهُۥ سَيُصِيبُ ٱلَّذِينَ أَجْرَمُوا۟ صَغَارٌ عِندَ ٱللَّـهِ وَعَذَابٌ شَدِيدٌۢ بِمَا كَانُوا۟ يَمْكُرُونَ

wa-idhā jāʾathum āyatun qālū lan nuʾmina ḥattā nuʾtā mithla mā ūtiya rusulu allāhi allāhu aʿlamu ḥaythu yajʿalu risālatahu sa-yuṣību lladhīna ajramū ṣaghārun ʿinda allāhi wa-ʿadhābun shadīdun bi-mā kānū yamkurūna

When there comes to them a sign (from Allah), They say: "We shall not believe until we receive one (exactly) like those received by Allah's messengers." Allah knoweth best where (and how) to carry out His mission. Soon will the wicked be overtaken by humiliation before Allah, and a severe punishment, for all their plots.
