On efficiency (note: Muslims are not exempted):

Ibn Omar reported that the messenger of Allah said: "People are like a hundred camels amongst whom you hardly find one fit for riding." (Agreed)

On our attitudes:

Abu Sayeed reported that the messenger of Allah said: "You shall follow the practices of those before you, inch by inch and mile by mile, to the degree that if they enter into the hole of a lizard, you will follow them." He was asked: "O messenger of Allah, are they the Jews and Christians?" He replied: "Who else?" (Agreed)

Ibn Omar reported that the messenger of Allah said: "When my nation will walk with vanity, and the sons of kings, the princes of Persia and Byzantine will serve them, Allah will give authority to the wicked over the good." (At - Tirmidhi)

On our results:

Thauban reported that the messenger of Allah said: "It is near that the nations will call one another against you just as the eaters call one another to their dishes." Somebody asked: "Is this because we will be few in numbers that day?" He said: "Nay, but that day you shall be numerous, but you will be like the foam of the sea, and Allah will take the fear of you away from your enemies and will place weakness into your hearts." Somebody asked: "What is this weakness?" He said: "The love of the world and the dislike of death." (Abu Daud)

Abu Hurairah reported that whilst the prophet, Allah blessed him and granted him peace, was talking, a Bedouin came to him and asked: "When will the hour come to pass?" He replied: "Wait for the hour when trust will be destroyed." He asked, how it would be destroyed, and he said: "Wait for the hour when the rule will be entrusted to those who don't deserve it." (Bukhari)

Anas reported that the messenger of Allah said: "The hour shall not come until time will be considered short, and a year will appear like a month, a month like a week, a week like a day, a day like an hour and an hour like a flash of fire." (Tirmidhi)

Abu Hurairah reported that the messenger of Allah said: "Hasten the good works before the advent of tribulations like pieces of dark night. A man will get up a believer in the morning and end the day as an unbeliever, or end his day a believer and get up an unbeliever next morning, selling his religion for a share of this world." (Muslim)

'Auf bin Malik reported: "I came to the Prophet, Allah blessed him and granted him peace, during the battle of Tabuk while he was in a leather tent, and he said: 'Count six things before the last hour: my death, then the conquest of Jerusalem, then the pestilence that will overtake you like the disease of cattle, then the excess of wealth, so much that when a man shall be given a hundred dinars he shall remain dissatisfied, then revolution from which not a single house in Arabia shall be spared, then a treaty between you and the Westerners (Banu Asfar - the Romans), but they shall cheat you and march against you under 80 banners with 12000 soldiers under each banner. (Bukhari)

What to expect next:

Abdullah bin Amr reported that the messenger of Allah said: "There will come a calamity which will wipe out the Arabs. Their slain will be in hell. The tongue will be more severe in this than the blow of the sword." (Tirmidhi, Ibn Majah)

Abu Hurairah reported that the messenger of Allah said: "The last hour shall not come to pass until two big parties will fight, and a great war will occur between them, and their claim will be one and the same; until nearly thirty lying Dajjals will be raised, each one of them claiming that he is the messenger of Allah; until knowledge will be held back and earthquakes will increase and time will become short and trials will appear, and killing will increase, and wealth will increase amongst you and overflow; until the owner of wealth will search to find somebody willing to accept charity, till when he gives it to somebody, that one will say: 'I have no need for it'; until people will compete with each other in building high buildings; until a man will pass by a grave and say: 'If only I were in his place'; until the sun will rise from its place of setting, and when the people will see it rise, they will all believe, and that will be when belief will not avail a soul that did not believe before or did good on account of its belief; and the hour shall come whilst two men have spread out their cloaks before them, but not yet sold them nor folded them up again; and the hour shall come whilst a man has taken the milk of his camel, but not yet tasted it; and the hour shall come when he repairs his container, but has not yet filled it with drink; and the hour shall come when he has raised a morsel to his mouth but not yet tasted it. (Agreed)

On the alternatives:

Ma'qal bin Yasar reported that the messenger of Allah said: "Prayer (Ibadah) at the time of turmoil is like migration (Hijrah) towards me." (Muslim)

'Omar bin al - Khattab reported that the messenger of Allah said: "Troubles will afflict my people in latter days from their rulers. None will escape from them except one who recognises Allah's religion and then fights for it with his tongue, hand and heart, and his reward will already be sure; and one who recognises the religion of Allah and holds on to it; and one who recognises the religion of Allah and keeps quiet about it - if he sees somebody who does good, he loves him, and if he sees somebody who does wrong, he is angry with him, he will be saved for all that he kept secret. (Baihaqi)

'Abdullah bin 'Amr reported that the prophet said: "How will it be with you if you are left amongst the scum of people whose covenants and trusts are loose and who will differ and become like this", and he interjoined his fingers. He asked: "What do you order me to do?" He said: "Keep to what you know, and reject what appalls you, and mind your own affairs and beware of public affairs." (Tirmidhi)

On Dajjal:

'Imran bin Hussain said: "I heard the messenger of Allah, Allah blessed him and gave him peace, say: 'Between the creation of Adam and the last hour there is no greater matter than the Dajjal." (Muslim) 

Nafe' bin 'Utbah reported that the messenger of Allah said: "You shall attack the peninsula of Arabia and Allah shall give you victory over it, and then Persia and Allah shall give you victory over it, then you shall attack Rome (Byzantine) and Allah shall give you victory over it, and then you shall attack the Dajjal and Allah shall give you victory over him. (Muslim)
