Narrated Abu Huraira: The Prophet said, "The Hour will not be established till there is a war between two groups among whom there will be a great number of casualties, though the claims (or religion) of both of them will be one and the same. And the Hour will not be established till there appear about thirty liars, all of whom will be claiming to be the messengers of Allah. "

Narrated Abu Huraira: The Prophet said, "(Religious) knowledge will be taken away (by the death of religious scholars) ignorance (in religion) and afflictions will appear; and Harj will increase." It was asked, "What is Harj, O Allah's Apostle?" He replied by beckoning with his hand indicating "killing." (Fath-al-Bari Page 192, Vol. 1)

Umar bin Al-Khattab said: I heard Hisham bin Al-Hakim reciting Surat Al-Furqan during the lifetime of Allah's Messenger (saws). I listened to his recitation and noticed that he recited it in several different ways which Allah's Messenger (saws) had not taught me. So I was about to jump over him during his Salat (prayer) but I waited till he finished his Salat (prayer) whereupon I put, either his upper garment or my upper garment around his neck and seized him by it and asked him, "Who has taught you this Surah?" He replied: "Allah's Messenger (saws) has taught it to me." I said (to him), "You have told a lie! By Allah, Allah's Messenger (saws) has taught me this Surah which I have heard you reciting." So I dragged him to the Allah's Messenger (saws). I said: "O Allah's Messenger I have heard this man reciting Surat Al-Furqan in a way in which you have not taught me, and you did teach me Surah Al-Furqan." On that Allah's Messenger (saws) said, "O 'Umar, release him! Recite, O Hisham". So Hisham recited before him in the way as I heard him reciting. Allah's Messenger (saws) said, "It has been revealed like this." Then Allah's Messenger (saws) said, "Recite, O 'Umar" So recited it. The Prophet (saws) said, "It has been revealed like this." And then he added, "This Qur'an has been revealed to be recited in seven different ways, so recite it whichever way is easier for you."

Narrated Abu Huraira: Allah's Apostle said, "The Hour will not be established (1) till two big groups fight each other whereupon there will be a great number of casualties on both sides and they will be following one and the same religious doctrine, (2) till about thirty Dajjals (liars) appear, and each one of them will claim that he is Allah's Apostle, (3) till the religious knowledge is taken away (by the death of Religious scholars) (4) earthquakes will increase in number (5) time will pass quickly, (6) afflictions will appear, (7) Al-Harj, (i.e., killing) will increase, (8) till wealth will be in abundance ---- so abundant that a wealthy person will worry lest nobody should accept his Zakat, and whenever he will present it to someone, that person (to whom it will be offered) will say, 'I am not in need of it, (9) till the people compete with one another in constructing high buildings, (10) till a man when passing by a grave of someone will say, 'Would that I were in his place (11) and till the sun rises from the West. So when the sun will rise and the people will see it (rising from the West) they will all believe (embrace Islam) but that will be the time when: (As Allah said,) 'No good will it do to a soul to believe then, if it believed not before, nor earned good (by deeds of righteousness) through its Faith.' (6.158) And the Hour will be established while two men spreading a garment in front of them but they will not be able to sell it, nor fold it up; and the Hour will be established when a man has milked his she-camel and has taken away the milk but he will not be able to drink it; and the Hour will be established before a man repairing a tank (for his livestock) is able to water (his animals) in it; and the Hour will be established when a person has raised a morsel (of food) to his mouth but will not be able to eat it."
