Concise Quran Commentary
Those who deny the resurrection on the Day of Rising, and regard standing before Allah to be farfetched, are in utter loss. Until, when the Hour comes upon them suddenly without any prior knowledge, they will say, because of extreme regret: Alas for us and what disappointment, due to our having been neglectful of Allah by disbelieving Him and not preparing for the Day of Rising. They will carry their evil actions on their backs. How terrible are those evil actions that they carry!
