هَلْ يَنظُرُونَ إِلَّآ أَن تَأْتِيَهُمُ ٱلْمَلَٰٓئِكَةُ أَوْ يَأْتِىَ رَبُّكَ أَوْ يَأْتِىَ بَعْضُ ءَايَٰتِ رَبِّكَ ۗ يَوْمَ يَأْتِى بَعْضُ ءَايَٰتِ رَبِّكَ لَا يَنفَعُ نَفْسًا إِيمَٰنُهَا لَمْ تَكُنْ ءَامَنَتْ مِن قَبْلُ أَوْ كَسَبَتْ فِىٓ إِيمَٰنِهَا خَيْرًۭا ۗ 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.
Surah Al-An'aam(6:158)
