A ---Allah the Almighty says: {Do they then wait for anything other than that the angels should come to them, or that your Lord (Allah) should come, or that some of the Signs of your Lord should come (i.e. portents of the Hour e.g., rising of the sun from the west)! The day that some of the Signs of your Lord do come, no good will it do to a person to believe then, if he believed it not before, nor earned good (by performing the deeds of righteousness) through his Faith. Say: "Wait you! We (too) are waiting}. (Al-An' am, 158)

Allah the Almighty says: {And when the Word (of torment) is fulfilled against them, We shall bring out from the earth a beast for them, to speak to them because mankind believed not with certainty in Our Ayat (verses of the Qur'an and Prophet Muhammad (Peace be upon him))}. (An-Naml, 82)

Allah the Almighty says: {Until, when Ya'juj and Ma 'juj (Gog and Magog) are let loose (from their barrier), and they swoop down from every mound. And the true promise (Day of Resurrection)

shall draw near (of fulfillment). Then (when mankind is resurrected from their graves), you shall see the eyes of the disbelievers fixedly staring in honor. (They will say): "Woe to us! We were indeed heedless of this -nay, but we were Zalimun (polytheists and wrong-doers)"}. (Al-Anbiya', 96, 97)

Allah the Almighty says: {Then wait you for the Day when the sky will bring forth a visible smoke}. (Ad-Dukhan, 10)

Allah the Almighty says: {O mankind! Fear your Lord and be dutiful to Him! Verily, the earthquake of the Hour (of Judgement) is a terrible thing. The Day you shall see it, every nursing mother will forget her nursling, and every pregnant one will drop her load, and you shall see mankind as in a drunken state, yet they will not be drunken, but severe will be the Torment of Allah}. (Al-Hajj, 1, 2)
