وَقَالَ ٱلَّذِينَ لَا يَعْلَمُونَ لَوْلَا يُكَلِّمُنَا ٱللَّهُ أَوْ تَأْتِينَآ ءَايَةٌۭ ۗ كَذَٰلِكَ قَالَ ٱلَّذِينَ مِن قَبْلِهِم مِّثْلَ قَوْلِهِمْ ۘ تَشَٰبَهَتْ قُلُوبُهُمْ ۗ قَدْ بَيَّنَّا ٱلْءَايَٰتِ لِقَوْمٍۢ يُوقِنُونَ
And those who have no knowledge say: Why doth not Allah speak unto us, or some sign come unto us? Even thus, as they now speak, spake those (who were) before them. Their hearts are all alike. We have made clear the revelations for people who are sure.
Surah Al-Baqara(2:118)
