Sayyiduna Uqbah bin Amir (may Allah be pleased with him) narrates that one day we prayed with the Prophet (peace and blessings of Allah be upon him), and he stood for a very long time. Then I saw that the Prophet (peace and blessings of Allah be upon him) stretched out his blessed hand as if to take hold of something. Then, when he finished the prayer with salam, he said: "Everything that you have been promised was shown to me at that moment—even Hell was shown to me, and a spark from it came towards me until it reached this place of mine, so I became afraid that it might engulf you."
