Hadith: The Hour will not come until the sun rises from the west, and when it rises and people see it, they will all believe

عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ:
«لاَ تَقُومُ السَّاعَةُ حَتَّى تَطْلُعَ الشَّمْسُ مِنْ مَغْرِبِهَا، فَإِذَا طَلَعَتْ فَرَآهَا النَّاسُ آمَنُوا أَجْمَعُونَ، فَذَلِكَ حِينَ: {لاَ يَنْفَعُ نَفْسًا إِيمَانُهَا لَمْ تَكُنْ آمَنَتْ مِنْ قَبْلُ، أَوْ كَسَبَتْ فِي إِيمَانِهَا خَيْرًا} [الأنعام: 158] وَلَتَقُومَنَّ السَّاعَةُ وَقَدْ نَشَرَ الرَّجُلاَنِ ثَوْبَهُمَا بَيْنَهُمَا فَلاَ يَتَبَايَعَانِهِ، وَلاَ يَطْوِيَانِهِ، وَلَتَقُومَنَّ السَّاعَةُ وَقَدِ انْصَرَفَ الرَّجُلُ بِلَبَنِ لِقْحَتِهِ فَلاَ يَطْعَمُهُ، وَلَتَقُومَنَّ السَّاعَةُ وَهُوَ يَلِيطُ حَوْضَهُ فَلاَ يَسْقِي فِيهِ، وَلَتَقُومَنَّ السَّاعَةُ وَقَدْ رَفَعَ أَحَدُكُمْ أُكْلَتَهُ إِلَى فِيهِ فَلاَ يَطْعَمُهَا».
[صحيح] - [متفق عليه] - [صحيح البخاري: 6506]

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said:
"The Hour will not come until the sun rises from the west, and when it rises and people see it, they will all believe. But that will be the time when {belief will be of no benefit to those who did not believe before, or those who did not do some good through their faith} [Surat al-An‘ām: 158]. The Hour will surely come (so suddenly) that two people spreading a garment between them will not be able to finish their bargain, nor will they be able to fold it up. The Hour will surely come when a man is carrying the milk of his she-camel, but he will not be able to drink it. The Hour will surely come when someone will not be able to prepare the tank to water his livestock from it. And the Hour will come when one of you has raised his food to his mouth but cannot eat it."
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Bukhari - 6506]

Explanation

The Prophet (may Allah's peace and blessings be upon him) reports that among the major portents of the Hour is that the sun will rise from the west instead of the east, and when people see it, they will all believe. At that point, the belief of a disbeliever will not benefit him, nor will the righteous deeds or repentance be of any avail. Then, the Prophet (may Allah's peace and blessings be upon him) mentioned that the Hour will come so abruptly that people will be busy with their life affairs. So, the Hour will come when a buyer and a seller have spread out a garment between them, but they cannot finish their transaction or fold up the garment. And the Hour will come when a man has taken milk from his she-camel but will not be able to drink it. And the Hour will come when a man is repairing his tank, but he will not be able to water his livestock therefrom. And the Hour will come when a man has lifted a morsel to his mouth but will not be able to eat it.
