Praise be to Allah, and peace and blessings be upon the Messenger of Allah.
Much of what circulates on social media concerning the signs of the Hour cannot be definitively declared to be one of the signs of the Hour. A Muslim should not build his fear and anxiety upon unverified reports and rumors.
As for what is said about the slowing of the Earth's inner core or a change in its direction of rotation, these are matters that have been studied and debated among specialists. It is not correct to link them to the rising of the sun from the west or to regard them as signs that the Hour is near.
As for what is called the Green Comet, according to the reports about it, it is a comet that travels through space and sometimes approaches Earth. There is no evidence that it is one of the signs of the Hour.
As for At-Tariq, mentioned in the words of Allah:
﴿By the sky and At-Tariq, And what can make you know what At-Tariq is? It is the piercing star.﴾ [At-Tariq: 1–3],
there is nothing in the Qur'an or Sunnah indicating that a particular star will come to Earth at the end of time. The view held by many commentators is that At-Tariq is a general name referring to stars that appear at night, rather than the name of a particular star that is expected to come to Earth.
As for the apparent enlargement of the lunar crescents, narrations concerning it have been mentioned among the signs of the Hour. However, scholars have discussed their authenticity: some considered them weak, while others strengthened them when their various chains of transmission are considered together. If they are considered authentic, what is meant is that the crescent appears on its first night in a form that makes it seem as though it is two nights old, rather than merely differences in people's observations or rumors circulating about the shape of the crescent.
The authentic signs of the Hour include those that have already occurred and those that have not yet occurred. Allah and His Messenger ﷺ informed us of them to alert people and encourage them to repent and prepare to meet Allah, not to plunge them into panic and distress.
Allah the Exalted says:
﴿The Hour has drawn near and the moon has split.﴾ [Al-Qamar: 1].
A believer should not allow his fear of the Hour to become a negative fear that prevents him from living his life and fulfilling his responsibilities. Rather, he should make it a beneficial fear that motivates him toward repentance, righteous deeds, and preparation for the Hereafter, while continuing to take care of his worldly responsibilities.
Among the teachings of the Prophet ﷺ is:
“If the Hour comes while one of you has a palm shoot in his hand, let him plant it.”
This indicates that a Muslim should not abandon beneficial work because of fear that the Hour is near.
As for excessive anxiety caused by following news about the end of the world on social media, it is better to stop following pages that spread frightening rumors and predictions, and not to become preoccupied with every natural or astronomical phenomenon and connect it to the signs of the Hour without evidence.
Rather, a Muslim should devote his time to what benefits him: the Qur'an, beneficial knowledge, worship, honoring one's parents, maintaining family ties, work, and permissible relaxation, and should not allow following news about the Hour to become a cause of panic and psychological distress.
In conclusion: It is not correct to regard every astronomical or geological phenomenon circulating on social media as a sign that the end of the world is near. There is no evidence that a star called “At-Tariq” will come to Earth. The duty is to believe in the established signs of the Hour, reject rumors, and prepare for the Hereafter through righteous deeds, without panic or neglecting one's worldly responsibilities.
And Allah knows best.
