No one but Allah knows when the Hour will come. However, much has been learned about some of the signs that will appear when the end comes closer. Of course, this information is mainly mentioned in the hadith of the Prophet Muhammad.
Judgment Day
The meaning of the word Judgment is to stand teak. Judgment Day is named after all those who will rise from the dead. Apart from the Day of Judgment there are several other names, such as the Day of Reckoning, the Hereafter, and the Day of Judgment.
When all the signs come to light, it is by God's will that this world will come to its end and that the Hour will come. Then life in all life ends. The present system of things is completely disrupted. Everything will be destroyed. That is the Day of Judgment.
Resurrection
A Muslim should have a firm belief in the resurrection of all those who have died on the Day of Judgment. We should not think that how does it come to life that a person will die after he dies, his body is covered with dust, burned by fire or fed by animals.
Account
A Muslim has to believe that in the Day of Judgment, what he has done in the world will be counted as a single particle and that he will be rewarded or punished accordingly.
Weighing scales and practices
The believer must be convinced that there will be scales on the Day of Resurrection and measured in it with the utmost clarity of what everyone does in this world. This is because the information in the Qur'an and Hadith came with clear phrases that do not carry any interpretation.
Sirat and passage from it
A believer must believe that a bridge called "Sirat" will be built over Hell on the Day of Judgment, that all people will be ordered to cross it, and some will be saved and some will fall into hell.
