The appearance of corruption at the end of time and the virtue of enjoining good at that time

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, everything has a rise and a decline, and indeed this religion too has a rise and a decline. The period of this religion's rise is that with which Allah Almighty has sent me, until a whole tribe, down to its last member, will gain understanding of the religion, so that none will remain among them except one or two sinners, and those two will also be overpowered, crushed and humiliated; if they speak or open their mouths, they will be suppressed, overpowered and persecuted. Then he (peace and blessings be upon him) mentioned the decline of this religion, saying: The whole tribe, down to its last member, will become ignorant and coarse, until none will remain among them except one or two men of understanding (faqih) in the religion, and those two will be overpowered, crushed and humiliated; if they speak or open their mouths, they will be suppressed, overpowered and persecuted, and it will be said to them: 'Are you rebelling against us?' Until wine will be drunk openly in their gatherings, assemblies and markets, and wine will be given another name and declared lawful, until the last people of this Ummah will curse its first people, except that the curse will then fall (for doing so) upon him who does it. And they will say: 'There is no harm in this drink.' A man among them will drink of it as much as he likes and then stop. Until matters will reach the point that when a woman passes by, that wicked man will get up towards her, lift her garment and commit fornication with her in public while the people watch, just as the tail of a ewe is lifted (the narrator said that at that moment he, peace and blessings be upon him, lifted a wrapper of his made of Suhuli cloth to show it). Then one of them, who would be considered most pious, will say: 'If only you had taken her aside from the road into some cover.' The one who says this will be as respected and high-ranking among them as Abu Bakr and Umar (may Allah be pleased with them both) are among you. So whoever reaches that time and enjoins good and forbids evil will have the reward of fifty of my Companions who believed in me and affirmed my truth."
This hadith is da'if (weak); its chain contains four weak narrators in succession.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to us: "Allah Almighty will grant you a firm footing and power in the land, and you will do in it all the deeds that Allah wills you to do. But when you fall into disobedience and sins there, your enemy will be given dominance over you, and they will (push you and) drive you back to the land of the Arabs." Sayyiduna Anas (may Allah be pleased with him) said: At that very moment I said: "O Messenger of Allah (peace and blessings be upon him)! How will the land of the Arabs be able to bear us (that is, how will there be room there for such a large population), when you have told us about the great number of the Muslims?" He (peace and blessings be upon him) said: "Allah Almighty will create means of provision for you there (from the unseen), just as He created them for the Children of Israel when they were wandering (in the wilderness of al-Tih)."
Imam Abu Ya'la narrated it in his Musnad. Its chain contains Ghassan bin al-Rabi' and Musa bin Khalaf al-Ammi, about whom there is criticism among the hadith scholars; however, the text of the hadith warns the Muslims of the dreadful consequences of sins.

It is narrated from Sayyiduna Ma'qil bin Yasar al-Muzani (may Allah be pleased with him): I heard the Messenger of Allah (peace and blessings be upon him) say: "Time will not come to an end until the Qur'an (its effect and influence) becomes worn out and old in the breasts of some groups of this Ummah, just as clothing becomes worn out; other things besides the Qur'an will become more pleasing and more wondrous to them. All their affairs will be based entirely on greed and covetousness, without the slightest fear of Allah mixed in. If they fall short in fulfilling any right of Allah Almighty, their souls will keep them deluded with false hopes and wishes; and if they commit any sin that Allah has forbidden, they will say (with great boldness): 'I hope that Allah Almighty will overlook this slip of mine.' Their hearts will be like those of wolves (hard and bloodthirsty), over which they will have put on cloaks like sheepskins (soft and simple). In their view, the best of them will be the one who is 'al-mudahin' (the one who compromises and indulges in misplaced expediency)."
It was asked what is meant by "al-mudahin", and he (peace and blessings be upon him) said: "The one who (out of expediency regarding circumstances) neither enjoins good nor forbids evil."
