Surah Al-An'am (The Cattle), Verse 124

وَاِذَا جَآءَتْهُمْ اٰیَةٌ قَالُوْا لَنْ نُّؤْمِنَ حَتّٰی نُؤْتٰی مِثْلَ مَاۤ اُوْتِیَ رُسُلُ اللّٰهِ اَللّٰهُ اَعْلَمُ حَیْثُ یَجْعَلُ رِسَالَتَهٗ سَیُصِیْبُ الَّذِیْنَ اَجْرَمُوْا صَغَارٌ عِنْدَ اللّٰهِ وَعَذَابٌ شَدِیْدٌۢ بِمَا كَانُوْا یَمْكُرُوْنَ ۟

Wa izaa jaaa'athum Aayatun qaaloo lan nu'mina hatta nu'taa misla maaa ootiya Rusulul laah; Allahu a'alamu haisu yaj'alu Risaalatah; sa yuseebul lazeena ajramoo saghaarun 'indal laahi wa 'azaabun shadeedum bimaa kaanoo yamkuroon

“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.”
