The following excerpt is taken from “The Holy Quran in Today’s English” by Yahiya Emerick note #721:
Surah 6 Verse # 158:
Are they waiting to see the angels coming for them, or your Lord, or the unmistakable signs of your Lord’s (coming)? On the day when the signs of your Lord do arrive, it won’t do any good for a soul to believe in them, if it hadn’t already believed in them or made a good account (of its sincerity) through (acts of) true faith. Say to them, “Wait, because we’ll be waiting, too.” 
 These are some of the foretold portents signaling the coming of the End Times. When these come to pass, then belief will not be accepted. Among these, the most significant one will be the appearance of a wicked leader known as the Dajjal, or Anti-Christ, who will dupe people into believing in him instead of God. The Prophet said, “When the following three signs appear, it won’t do anyone any good to believe unless they had already believed before. They are the rising of the sun from the West, the Dajjal, and the rising of a beast from the earth.” (Muslim) The first sign has been interpreted to mean that the West becomes more powerful than the Eastern (or Islamic) world, while the third sign remains enigmatic and is steeped in mysterious symbolism. See 27:82 and footnote for more on the beast.
