Surah Al-A'raf (The Heights), Verse 171

وَاِذْ نَتَقْنَا الْجَبَلَ فَوْقَهُمْ كَاَنَّهٗ ظُلَّةٌ وَّظَنُّوْۤا اَنَّهٗ وَاقِعٌ بِهِمْ خُذُوْا مَاۤ اٰتَیْنٰكُمْ بِقُوَّةٍ وَّاذْكُرُوْا مَا فِیْهِ لَعَلَّكُمْ تَتَّقُوْنَ 

Wa iz nataqnal jabala fawqahum ka annahoo zullatunw wa zannooo annahoo waaqi'un bihim khuzoo maaa aatainaakum biquwwatinw wazkuroo maa feehi la'allakum tattaqoon

“When We shook the Mount over them, as if it had been a canopy, and they thought it was going to fall on them (We said): "Hold firmly to what We have given you, and bring (ever) to remembrance what is therein; perchance ye may fear Allah."”
