Major Signs before the Day of Judgement(8.Rising of the Sun from the West)

The rising of the sun from the west is also a major sign of Qiyamah 
proven by the Qur'an and Sunnah.

Allah says in the Qur'an, "The day when some signs of your Lord will 
come, no good will it do to a person to believe then, if he believed not before, nor earned good (by performing deeds of righteousness) through his faith." 
(Surah Al-An'aam)

The verse is referring to the rising of the sun from the west, as is 
the opinion of the majority of the commentators. (Tabari/Ibne Kathir)

Imam Tabari, after mentioning the different opinions of the 
commentators writes, "The most correct opinion in regards to the meaning 
of this verse is that what is apparent from the reports narrated from 
the Prophet Peace and blessings be upon him that he Peace and blessings
 be upon himsaid, "(lmaan will be of no benefit) when the sun rises from 
the west." (Tabari)

Abu Huraira reported that the Holy Prophet Peace and blessings be
 upon him said, "Hasten to do good deeds before six (things happen)
 :Rising of the sun from the west." (Mishkat)
  

Where the Sun Goes

It is narrated on the authority of Abu Zar that the Messenger of
 Allah Peace and blessings be upon him one day said, "Do you know 
where the Sun goes?" They replied, "Allah and his apostle know best." 
He (The Holy Prophet Peace and blessings be upon him) observed, 
"Verily it (the sun) glides till it reaches its resting place under the throne. Then it falls prostrate and remains there until it is told, 'Rise up and 
go to the place whence you came' and it goes back."

Then it continues emerging out from its rising place and then glides 
till it reaches its place of rest under the throne where it falls prostrate 
and remains in that state until it is told, 'Rise up and return to the place whence you came.' And it returns and emerges out of it's rising place 
and then it glides (in such a normal way) that the people do not discern anything (unusual in it) till it reaches its resting place under the throne. Then it would be said to it, 'Rise up and emerge from the place of your setting,' and it will rise from the place of its setting." 
The Messenger of Allah Peace and blessings be upon him said "Do you
 know when it will happen? It will happen at the time when faith will 
not benefit anyone who has not previously believed or has derived no
 good from the faith." (Muslim)

Worshippers during the night will remain till the sun rises from the
 WestAbdullah-b-Abu-Owfa reported that I heard the Messenger of
 Allah Peace and blessings be upon him say, "Verily a night will come 
upon the people which is equivalent of three of your nights. When it 
comes those that engage themselves in worship during the night will recognise it. One of them will stand in prayer, read his Hizb (The 
normal amount he has made the habit of reading) and then go to sleep. Thereafter he will wake up (for the second time) read his Hizb in
 prayer and go to sleep. While this is the situation the people will begin 
to shout, scream and call one another. They will say, "What's this?" With fear they will run to the mosque. To their surprise they will see that the sun has risen from the west. When it reaches the middle of the sky it
 will return and set in the west." He said Peace and blessings be upon 
him, "That is when Imaan will not benefit anyone (who brings faith 
after seeing the sign)." (An-Nihaya)
    

Everyone will bring Faith in Seeing The Sign***

Narrated by Abu Huraira (R.A), "Allah's Messenger Peace and 
blessingsbe upon him said, 'The hour will not come until the sun rises 
from the west;
 and when the people see it, then whoever will be living on the
 surface of the Earth will have faith, and that is (the time) when 
no good will it do to a person to believe then, if he believed 
not before." (Bukhari)

The real basis of faith is that man believes in the unseen realities
 onthe authority of the Messenger of Allah Peace and blessings be upon 
him. But when Allah manifests such startling and visible signs which herald the approach of the last hour and by which the veil of the
 unseen is rent asunder, then the belief becomes meaningless. 
 The rising of the sun from the west will be of great disturbance to 
nature and will shake the mind of every man and awaken him to see 
for himself the great power of Allah.  
At this time the belief of the unseen will lose its importance.
 

*Door of Repentance Closed*

Once the sun has risen from the west the door of repentance will
 be closed and will remain closed until the Day of Judgement. If any
 infidel embraces Islam or any Muslim repents and seeks forgiveness
 for his sins any time after the rising of the sun from the west till the 
Day of Judgement, it will not be accepted.

The Messenger of Allah Peace and blessings be upon him said, "Verily 
Allah extends his hand at night so that the sinners of the day may repent and verily extends his hand during the day so that the sinners of the 
night may repent. (He will keep on doing this) as long as the sun does 
not rise from the west." (Abu-Musa al-Ashari/ Muslim)

The Prophet Peace and blessings be upon him said, "Allah has built a
 door of repentance in the west the breadth of which is seventy years 
and it will not close as long as the sun does not rise from the west." 
(Safwan-b-Assal / Tirmidhi)

The above Ahadith have clearly specified that the extreme limit of the acceptance of repentance is till the sun rises from the west. Once it has 
risen it will not be accepted.

Ibne Hajar has mentioned many Ahadith which prove that the door 
of repentance will remain closed till the Day of Judgement and 
thereafter writes, ''These narration's give strength to one another, agreeing completely in that when the sun rises from the west the door of
 repentance will be closed and will not be opened thereafter. And this is
 not specific with that day but will prolong till the Day of Judgement.'' (Fathul- Bari)
