وَيَقُولُونَ لَوْلاَ أُنزِلَ عَلَيْهِ آيَةٌ مِّن رَّبِّهِ فَقُلْ إِنَّمَا الْغَيْبُ لِلّهِ فَانْتَظِرُواْ إِنِّي مَعَكُم مِّنَ الْمُنتَظِرِينَ
[10:20]
And they say: Why is not a sign sent to him from his Lord? Say: The unseen is only for Allah; therefore wait-- surely I too, with you am of those who wait.
They say: "Why is not a sign sent down to him from his Lord?" Say: "The Unseen is only for Allah (to know), then wait ye: I too will wait with you."
And they will say: If only a portent were sent down upon him from his Lord! Then say, (O Muhammad): The Unseen belongeth to Allah. So wait! Lo! I am waiting with you.
