Surah Yunus, Verse 20

وَيَقُولُونَ لَوۡلَآ أُنزِلَ عَلَيۡهِ ءَايَةࣱ مِّن رَّبِّهِۦۖ فَقُلۡ إِنَّمَا ٱلۡغَيۡبُ لِلَّهِ فَٱنتَظِرُوٓاْ إِنِّي مَعَكُم مِّنَ ٱلۡمُنتَظِرِينَ ﴿٢٠﴾

Ve yekulune lev la ünzile aleyhi ayetüm mir rabbih fe kul innemel ğaybü lillahi fentezıru innı meaküm minel müntezırın

“They say: "Why is not a sign sent down to him from his Lord?" Say: "The Unseen is only for God (to know), then wait ye: I too will wait with you”
