Allaah (subhaanahu wa ta'aala) said:
"They ask you (O Muhammad sal-Allaahu 'alayhe wa sallam) about the
Hour, - when will be its appointed time? You have no knowledge to say
anything about it, To your Lord belongs (the knowledge of) the term
thereof? You (O Muhammad sal-Allaahu 'alayhe wa sallam) are only a
warner for those who fear it, The Day they see it, (it will be) as if they had
not tarried (in this world) except an afternoon or a morning." [An-Nazi'aat
(79):42-46]
"They ask you about the Hour (Day of Resurrection): 'When will be its
appointed time?' Say: 'The knowledge thereof is with my Lord (Alone).
None can reveal its time but He. Heavy is its burden through the heavens
and the earth. It shall not come upon you except all of a sudden.' They
ask you as if you have a good knowledge of it. Say: 'The knowledge
thereof is with Allaah (Alone) but most of mankind know not.''" [Al-A'raaf
(7):187]
There are many Ayaat and Ahaadeeth concerning this subject: Allaah
said:

"The Hour has drawn near, and the moon has been cleft asunder." [Al-
Qamar (54):1]

The Prophet (sal-Allaahu 'alayhe wa sallam) said, whilst pointing with his
index and middle fingers,
"The time of my advent and the Hour are like these two fingers." [1]
In another report he said,
"The Hour almost came before me."
This indicates how close we are, relatively speaking, to the Hour.
Allaah said:
"Draws near for mankind their reckoning, while they turn away in
heedlessness." [Al-Anbiyaa' (21):1]
"The Event (the Hour or the punishment of disbelievers and polytheists or
the Islaamic laws or commandments), ordained by Allaah will come to
pass, so seek not to hasten it. Glorified and Exalted be He above all that
they associate as partners with Him." [An-Nahl (16):1]
