Quran 10:20 from Surah Yunus on Divine Marvels.
وَيَقُولُونَ لَوۡلَآ أُنزِلَ عَلَيۡهِ ءَايَةٞ مِّن رَّبِّهِۦۖ فَقُلۡ إِنَّمَا ٱلۡغَيۡبُ لِلَّهِ فَٱنتَظِرُوٓاْ إِنِّي مَعَكُم مِّنَ ٱلۡمُنتَظِرِينَ
English translation: And they say Why not is sent down to him a Sign from his Lord So say Only the unseen (is) for Allah so wait indeed I am with you among the ones who wait
Transliteration: wayaquluna lawla unzila alayhi ayatun min rabbihi faqul innama al-ghaybu lillahi fa-intaziru inni ma'akum mina al-muntazirina
