Al-An'am - 6:158

هَلْ يَنظُرُونَ إِلاَّ أَن تَأْتِيهُمُ الْمَلآئِكَةُ أَوْ يَأْتِيَ رَبُّكَ أَوْ يَأْتِيَ بَعْضُ آيَاتِ رَبِّكَ يَوْمَ يَأْتِي بَعْضُ آيَاتِ رَبِّكَ لاَ يَنفَعُ نَفْسًا إِيمَانُهَا لَمْ تَكُنْ آمَنَتْ مِن قَبْلُ أَوْ كَسَبَتْ فِي إِيمَانِهَا خَيْرًا قُلِ انتَظِرُواْ إِنَّا مُنتَظِرُونَ
[6:158]
They do not wait aught but that the angels should come to them, or that your Lord should come, or that some of the signs of your Lord should come. On the day when some of the signs of your Lord shall come, its faith shall not profit a soul which did not believe before, or earn good through its faith. Say: Wait; we too are waiting.
Are they waiting to see if the angels come to them, or thy Lord (Himself), or certain of the signs of thy Lord! the day that certain of the signs of thy Lord do come, no good will it do to a soul to believe in them then if it believed not before nor earned righteousness through its faith. Say: "Wait ye: we too are waiting."
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.
