At-Tur 52:38

أَمْ لَهُمْ سُلَّمٌۭ يَسْتَمِعُونَ فِيهِ ۖ فَلْيَأْتِ مُسْتَمِعُهُم بِسُلْطَٰنٍۢ مُّبِينٍ

Am lahum sullamuny yastami'oona feehi falyaati mustami'uhum bisultaanim mubeen

Or have they a ladder, by which they can (climb up to heaven and) listen (to its secrets)? Then let (such a) listener of theirs produce a manifest proof.
