Qur'an 9:52

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

“Say, "Do you await for us except one of the two best things [i.e., martyrdom or victory] while we await for you that Allāh will afflict you with punishment from Himself or at our hands? So wait; indeed we, along with you, are waiting."”
