Al-Isra' - 17:93

أَوْ يَكُونَ لَكَ بَيْتٌ مِّن زُخْرُفٍ أَوْ تَرْقَى فِي السَّمَاء وَلَن نُّؤْمِنَ لِرُقِيِّكَ حَتَّى تُنَزِّلَ عَلَيْنَا كِتَابًا نَّقْرَؤُهُ قُلْ سُبْحَانَ رَبِّي هَلْ كُنتُ إَلاَّ بَشَرًا رَّسُولاً
[17:93]
Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal messenger?
"Or thou have a house adorned with gold, or thou mount a ladder right into the skies. No, we shall not even believe in thy mounting until thou send down to us a book that we could read." Say: "Glory to my Lord! Am I aught but a man,- a messenger?"
Or thou have a house of gold; or thou ascend up into heaven, and even then we will put no faith in thine ascension till thou bring down for us a book that we can read. Say (O Muhammad): My Lord be Glorified! Am I aught save a mortal messenger?
