يَٰمَعْشَرَ ٱلْجِنِّ وَٱلْإِنسِ إِنِ ٱسْتَطَعْتُمْ أَن تَنفُذُوا۟ مِنْ أَقْطَارِ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ فَٱنفُذُوا۟ ۚ لَا تَنفُذُونَ إِلَّا بِسُلْطَٰنٍۢ
O company of jinn and men, if ye have power to penetrate (all) regions of the heavens and the earth, then penetrate (them)! Ye will never penetrate them save with (Our) sanction.
