Surah Al-A'raaf, Verse 171
۞ وَإِذْ نَتَقْنَا ٱلْجَبَلَ فَوْقَهُمْ كَأَنَّهُۥ ظُلَّةٌۭ وَظَنُّوٓا۟ أَنَّهُۥ وَاقِعٌۢ بِهِمْ خُذُوا۟ مَآ ءَاتَيْنَٰكُم بِقُوَّةٍۢ وَٱذْكُرُوا۟ مَا فِيهِ لَعَلَّكُمْ تَتَّقُونَ
Translation — Sahih International
And [mention] when We raised the mountain above them as if it was a dark cloud and they were certain that it would fall upon them, [and Allah said], "Take what We have given you with determination and remember what is in it that you might fear Allah."
