What are the signs of the Day of Judgement (Qiyamah)?

There are many minor and major signs of the Final Hour. It is only Allah Who knows its timing, as the Qur'an mentions: "People ask you concerning the Final Hour. Say to them, 'The information about it is kept with Allah alone. What do you know? It may be forthcoming.'" [Qur'an, al-Ahzab 33:63]

The minor signs are the advent of the Beloved Prophet Muhammad ﷺ, the fire which will erupt in the Hijaz Province, contraction of time, speaking of inanimate things and animals, the competing of the shepherds in erecting tall buildings, vain glory of people over building fancy mosques, prevalence of commotion, excessive murders and prevalence of fornication.

The major signs include the advent of the Dajjal (Pseudo-Messiah), an impostor who would claim to be god, whose followers will be mostly Jews. This would be a time of great trial for the believers, as he could bring rain and make the earth produce. Then, there would be the descent of Eesa peace be upon him, Jesus, from the heaven.

There are other signs as indicated by the Beloved Prophet ﷺ: "The Final Hour will not come to pass until you witness ten signs of which are, the rising of the sun from the West, the smoke, the emergence of the Beast from the earth, the appearance of Yajuj Majuj, the descending of Eesa, son of Maryam from heaven, the appearance of the Dajjal, and three earthquakes; one in the East, one in the West, and the third in the Arabian Peninsula and a fire which will erupt from underground in Aden to drive people to the Assembly Land. It will accompany them, stopping wherever they stop, day and night." [Sahih Muslim 2901]
