Qur'an 6:158

هَلْ يَنظُرُونَ إِلَّآ أَن تَأْتِيَهُمُ ٱلْمَلَـٰٓئِكَةُ أَوْ يَأْتِىَ رَبُّكَ أَوْ يَأْتِىَ بَعْضُ ءَايَـٰتِ رَبِّكَ ۗ يَوْمَ يَأْتِى بَعْضُ ءَايَـٰتِ رَبِّكَ لَا يَنفَعُ نَفْسًا إِيمَـٰنُهَا لَمْ تَكُنْ ءَامَنَتْ مِن قَبْلُ أَوْ كَسَبَتْ فِىٓ إِيمَـٰنِهَا خَيْرًا ۗ قُلِ ٱنتَظِرُوٓا۟ إِنَّا مُنتَظِرُونَ

Wait they, indeed, for nothing less than that the angels should come unto them, or thy Lord should come, or there should come one of the portents from thy Lord? In the day when one of the portents from thy Lord cometh, its belief availeth naught a soul which theretofore believed not, nor in its belief earned good (by works). Say: Wait ye! Lo! We (too) are waiting.
