أَمۡ لَهُمۡ سُلَّمٞ يَسۡتَمِعُونَ فِيهِۖ فَلۡيَأۡتِ مُسۡتَمِعُهُم بِسُلۡطَٰنٖ مُّبِينٍ
Am lahum sullamuny yastami'oona feehi falyaati mustami'uhum bisultaanim mubeen
English Translation
Or have they a stairway [into the heaven] upon which they listen? Then let their listener produce a clear authority
