These are the signs which happen before the Day of Judgement, but not too close to its time; rather, they happen at different times. Some of them have already occurred and include the following:
The splitting of the moon:
The Qur'an says,"The Hour has come near, and the moon has split [in two]." (Surat Al-Qamar, 54:1). This happened at the time of the Prophet (pbuh) and everyone saw it.
The fight against the Moguls and the Tartars:
The Prophet (pbuh) said, "The Hour will not come until you fight a people wearing hairy shoes, and until you fight the Turks who have small eyes, red faces and flat noses, and their faces will be like flat shields." (Reported by Al-Bukhaaree)
The Fire of Hijaz:
The Prophet (pbuh) said, "The Hour will not come until a fire comes out of the land of Hijaz which will throw light on the camels' necks in Basra." (Reported by Al-Bukhaaree)
The end of the Persian and Roman rule:
The Prophet (pbuh) said, "When Khosrau perishes, there will be no more Khosrau after him; and when Caesar perishes, there will be no more Caesar after him." (Reported by Al-Bukhaaree)
There are many other minor signs which can be seen today. The Prophet (pbuh) said, "Among the signs of the Hour are (the following:) religious knowledge will be taken away, ignorance [of religion] will prevail, the drinking of alcaholic drinks will prevail and adultery will become rampant." (Reported by Al-Bukhaaree and Muslim)
