Commentary
The lexical item اشراط "ashrat" occurring in this passage means "signs". The portents of the last Hour starts with the very advent of Khatam-un-Nabiyyin ﷺ [ the Last of the Holy Prophets ] as the end of the Holy Prophethood is the sign of the approach of the last Hour. The miracle of the splitting of the moon by the Holy Prophet ﷺ has been described thus in the Holy Qur'an [ 54:1]: اقْتَرَبَتِ السَّاعَةُ "The hour has drawn near and the moon has split." - indicating that this miracle is also one of the signs of the last Hour. These are initial portents of the Hour which appeared at the time of the revelation of the Qur'an. Besides, there are many other portents that have been predicted in authentic Ahadith, one of which is reported by Anas in which he says that I have heard the Messenger of Allah ﷺ say: "Among the signs of the last hour is the removal of knowledge, abundance of ignorance, the prevalence of fornication, the prevalence of wine-drinking, the small number of men and the large number of women so that fifty women will have one man to look after them". (Bukhari and Muslim) A version has "knowledge will dwindle and ignorance will be widespread."
Abu Hurayrah ؓ reports Allah's Messenger ﷺ as saying: "When the spoils of war are taken as personal wealth, property given in trust is treated as spoil, zakah is treated as a fine, learning is acquired for other than religious purpose, a man obeys his wife and is undutiful towards his mother, brings his friend near and drives his father far off, voices are raised in the mosques, the most wicked member of a tribe becomes its ruler, the most worthless member of a people becomes its leader, a man is honored through fear of the evil he may do, singing-girls and stringed-instruments make their appearance, wines are drunk, and the last members of this community curse the earlier ones, look at that time for a violent wind, an earthquake, being swallowed up by the earth, metamorphosis, pelting rain, and signs following one another like bits of a necklace falling one after the other when its string is cut.
