GodlyVerses

[94]They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?"
[95]He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam.
[96]Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper."
[97]So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration.
[98][Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true."
[99]And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly.
[100]And We will present Hell that Day to the Disbelievers, on display - - Quran Al-Kahf(The Cave) 18:94-100 (islam)

"Gog and Magog people will be set free and they will
emerge as Allah says: "swoop(ing) down from every mound."[21:96]
They
will spread throughout the earth, and the Muslims will flee from
them
until the remainder of the Muslims are in their cities and
fortresses,
taking their flocks with them. They will pass by a river
and drink
from it, until they leave nothing behind, and the last of
them will
follow in their footsteps and one of them will say: 'There
was once
water in this place.' They will prevail over the earth, then
their
leader will say: 'These are the people of the earth, and we
have
finished them off. Now let us fight the people of heaven!' Then
one
of them will throw his spear towards the sky, and it will come
back
down smeared with blood. And they will say: 'We have killed the
people of heaven.' While they are like that, Allah will send a worm
like the worm that is found in the noses of sheep, which will
penetrate their necks and they will die like locusts, one on top of
another. In the morning the Muslims will not hear any sound from
them,
and they will say: 'Who will sell his soul for the sake of
Allah and
see what they are doing?' A man will go down, having
prepared himself
to be killed by them, and he will find them dead, so
he will call out
to them: 'Be of good cheer, for your enemy is dead!'
Then the people
will come out and let their flocks loose, but they
will not have
anything to graze on except their flesh, and they will
become very fat
as if they were grazing on the best vegetation they
ever found.'" - Hadith Ibn Majah 4079 (islam)

[95]And there is prohibition upon [the people of] a city which We have destroyed that they will [ever] return
[96]Until when [the dam of] Gog and Magog has been opened and they, from every elevation, descend
[97]And [when] the true promise has approached; then suddenly the eyes of those who disbelieved will be staring [in horror, while they say], "O woe to us; we had been unmindful of this; rather, we were wrongdoers."
[98]Indeed, you [disbelievers] and what you worship other than Allah are the firewood of Hell. You will be coming to [enter] it. - Quran Al-Anbya(The Prophets) 21:95-98 (islam)

“The Messenger of
Allah
(ﷺ) woke up red in the face and said: ‘La ilaha illallah,
woe to the
Arabs from an evil that has drawn nigh. Today a hole has
been opened
in the barrier of Gog and Magog.’ And he gestured to
indicate the size
of the hole.” Zainab said: “I said: ‘O
Messenger of Allah! Will we be
destroyed when there are righteous
people among us?’ He said: ‘If sin
and evil deeds increase.’” - Hadith Ibn Majah 3953 (islam)

"The Muslims will use the bows, arrows and shields
of Gog
and Magog as firewood, for seven years.'" - Hadith Ibn Majah 4076 (islam)
Book 36, Hadith 151
Vol. 5, Book 36, Hadith 4076

The Prophet (ﷺ) said, "On the day of Resurrection Allah will say, 'O Adam!' Adam will reply, 'Labbaik
our Lord, and Sa`daik ' Then there will be a loud call (saying), Allah orders you to take from among
your offspring a mission for the (Hell) Fire.' Adam will say, 'O Lord! Who are the mission for the
(Hell) Fire?' Allah will say, 'Out of each thousand, take out 999.' At that time every pregnant female
shall drop her load (have a miscarriage) and a child will have grey hair. And you shall see mankind as
in a drunken state, yet not drunk, but severe will be the torment of Allah." (22.2) (When the Prophet (ﷺ)
mentioned this), the people were so distressed (and afraid) that their faces got changed (in color)
whereupon the Prophet (ﷺ) said, "From Gog and Magog nine-hundred ninety-nine will be taken out and
one from you. You Muslims (compared to the large number of other people) will be like a black hair
on the side of a white ox, or a white hair on the side of a black ox, and I hope that you will be onefourth
of the people of Paradise." On that, we said, "Allahu-Akbar!" Then he said, "I hope that you
will be) one-third of the people of Paradise." We again said, "Allahu-Akbar!" Then he said, "(I hope
that you will be) one-half of the people of Paradise." So we said, Allahu Akbar." - Hadith Al Bukhari 4741 (islam)
