﴿ قُلْ هَلْ تَرَبَّصُونَ بِنَآ إِلَّآ إِحْدَى ٱلْحُسْنَيَيْنِ ۖ وَنَحْنُ نَتَرَبَّصُ بِكُمْ أَن يُصِيبَكُمُ ٱللَّهُ بِعَذَابٍۢ مِّنْ عِندِهِۦٓ أَوْ بِأَيْدِينَا ۖ فَتَرَبَّصُوٓا۟ إِنَّا مَعَكُم مُّتَرَبِّصُونَ ﴾

“Say: "Are you, perchance, hopefully waiting for something [bad] to happen to us-[the while nothing can happen to us] save one of the two best things? But as far as you are concerned, we are hopefully waiting for God to inflict chastisement upon you, [either] from Himself or by our hands! Wait, then, hopefully; behold, we shall hopefully wait with you!"”
