Quran 9:52 from Surah At-Tawba on Divine Marvels.
قُلۡ هَلۡ تَرَبَّصُونَ بِنَآ إِلَّآ إِحۡدَى ٱلۡحُسۡنَيَيۡنِۖ وَنَحۡنُ نَتَرَبَّصُ بِكُمۡ أَن يُصِيبَكُمُ ٱللَّهُ بِعَذَابٖ مِّنۡ عِندِهِۦٓ أَوۡ بِأَيۡدِينَاۖ فَتَرَبَّصُوٓاْ إِنَّا مَعَكُم مُّتَرَبِّصُونَ
English translation: Say Do you await for us except one (of) the two best (things) while we [we] await for you that Allah will afflict you Allah will afflict you with a punishment from [near] Him or by our hands So wait indeed, we with you (are) waiting
Transliteration: qul hal tarabbasuna bina illa ih'da al-hus'nayayni wanahnu natarabbasu bikum an yusibakumu al-lahu bi'adhabin min indihi aw bi-aydina fatarabbasu inna ma'akum mutarabbisuna
