أَمۡ لَهُمۡ سُلَّمٞ يَسۡتَمِعُونَ فِيهِۖ فَلۡيَأۡتِ مُسۡتَمِعُهُم بِسُلۡطَٰنٖ مُّبِينٍ ٣٨
Or have they a stairway [into the heaven] upon which they listen? Then let their listener produce a clear authority [i.e., proof].
Translation: Saheeh International (English)
Each word's meaning and sound
Or do they have a ladder with which to climb to the sky in which they listen to Allah’s revelation which He sends to tell them they are on the truth? So let the one who listens amongst them to that revelation bring a clear proof to affirm you in your claim that you are on truth.
