اقرأ وتدبر الآية 4773 من سورة سُورَةُ الطُّورِ: أَمْ لَهُمْ سُلَّمٌ يَسْتَمِعُونَ فِيهِ ۖ فَلْيَأْتِ مُسْتَمِعُهُمْ بِسُلْطَانٍ مُبِينٍ
أَمْ لَهُمْ سُلَّمٌ يَسْتَمِعُونَ فِيهِ ۖ فَلْيَأْتِ مُسْتَمِعُهُمْ بِسُلْطَانٍ مُبِينٍ
Or have they a ladder by which they could [ascend to ultimate truths and] listen [to what is beyond the reach of human perception]? Let, then, any of them who have listened [to it] produce a manifest proof [of his knowledge]!
