The Poets - 26:187
"They said, "Send down upon us the masses from the sky if you are truthful."
The disbelievers do not believe even if they see a miracle:
The Night Journey/17:92
Or you should make pieces of the sky fall on us, as you claim, or you should bring Allah and the angels before us.
The Poets/26:187
"They said, "Send down upon us the masses from the sky if you are truthful."
The Mountain/52:44
"And if they see a particle fall from the sky, they say: "It is a cloud!"
The Cattle/6:35
If their turning away is too much for you, know that even if you had the power to make a hole in the earth or a ladder in the sky, it would not profit you if you presented a miracle. Had Allah willed, He would have guided them. So do not be among the ignorant.
The Rocky Tract/15:14
If We had opened for them a door from the sky and they would have ascended in it,
The Rocky Tract/15:15
"They will say, "Our eyes have been intoxicated, we have been bewitched."
The Heights/7:146
I will turn away from My miracles those who are unjustly arrogant in the earth. Even if they see all kinds of miracles, they will not believe. If they see the right path, they do not follow it. But if they see the way of transgression, they follow it. For they denied Our Verses and paid no heed.
