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,1 [and Allāh said], "Take what We have given you with determination and remember what is in it that you might fear Allāh."
Mention, O Muhammad, when Allah raised the mountain above the Israelites when they refused to accept what was in the Torah. Then the mountain became like a cloud, casting a shadow over them, and they were sure it would fall upon them. They were told to firmly and seriously hold onto what Allah had revealed to them, and to remember the rulings that He had made law for them, and not to forget this, so that they might be Mindful.
