(And they will say) i.e. the disbelievers of Mecca: (If only a portent) a sign (were sent down upon him) i. e. to Muhammad (pbuh) (from his Lord!) to vouchsafe his claim. (Then say) O Muhammad: (The Unseen) regarding the sending of such a sign (belongeth to Allah. So wait) for my destruction! (Lo, I am waiting with you) for your destruction.

وَيَقُولُونَ لَوْلَا أُنْزِلَ عَلَيْهِ آيَةٌ مِنْ رَبِّهِ ۖ فَقُلْ إِنَّمَا الْغَيْبُ لِلَّهِ فَانْتَظِرُوا إِنِّي مَعَكُمْ مِنَ الْمُنْتَظِرِينَ
They say: "How is it that no sign was sent by his Lord (to His Prophet)?" Tell them: "Unknown things are only known to God. So watch and wait (for the sign); I am waiting and expecting with you."
