Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said, concerning the saying of Allah Almighty: "Are they waiting for anything except that the angels should come to them, or your Lord should come, or some of the signs of your Lord should come? On the Day when some of the signs of your Lord come, no soul will benefit from its faith if it had not believed before" [Surah al-An'am: 158]: "The rising of the sun together with the moon from the west, like two camels yoked together."
