أَوْ يَكُونَ لَكَ بَيْتٌ مِّن زُخْرُفٍ أَوْ تَرْقَىٰ فِي السَّمَاءِ وَلَن نُّؤْمِنَ لِرُقِيِّكَ حَتَّىٰ تُنَزِّلَ عَلَيْنَا كِتَابًا نَّقْرَؤُهُ ۗ قُلْ سُبْحَانَ رَبِّي هَلْ كُنتُ إِلَّا بَشَرًا رَّسُولًا
“Or you have a house of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read.' Say, 'Exalted is my Lord! Was I ever but a human messenger?'”
This ayah is part of the passage in Surah al-Isra (17:90-93) listing the specific miracles the Quraysh demanded before they would believe -- described at this event.
