﴿ فَهَلْ يَنتَظِرُونَ إِلَّا مِثْلَ أَيَّامِ ٱلَّذِينَ خَلَوْا۟ مِن قَبْلِهِمْ ۚ قُلْ فَٱنتَظِرُوٓا۟ إِنِّى مَعَكُم مِّنَ ٱلْمُنتَظِرِينَ ﴾

“Can such, then, expect anything else [to befall them] but the like of the days of [calamity which befell] those [deniers of the truth] who passed away before them? Say: "Wait, then, [for what will happen) verily, I shall wait with you!"”
