Wolves will give readings in the End Times. Let those who live to see those times seek shelter from their evil in God. They will be very corrupt people. Hypocrisy will prevail, and nobody will be ashamed of it and its manifestations. (Tirmidhi)

God's Messenger (may God bless him and grant him peace) said: "A man will wake up as a believer, and be an unbeliever by nightfall. People will sell their religion for a small amount of wordly goods." (Ibn Ahmad Hanbal)

He said: "In mosques, the voices of those who rebel aganist God rise, and those who commit those deeds prohibited by religion hold control over sincere believers." (Mukhtasar Tazkirah al-Qurtubi, p. 450, no. 828)

Ultimately some ignorant people remain. When they are asked about religious issues, they give a fatwa ]juridical decision], although they are illiterate. This way, they pervert and also make others stray from the right path. (Mukhtasar Tazkirah al-Qurtubi, p. 463, no. 850)

What a pity for my community, because of the scholars who have gone astray! These are the people who make religion a matter of commerce. They approach the chiefs of their time to earn their living. (al-Hatim)

A time will come when everyone will read the Qur'an, perform their acts of worship, and, meanwhile, engage in bid`a [innovation in worship that must be avoided]. Yet little do they know that they become idolaters in a way of which they are unaware. They earn money in return for their reading and knowledge, and consume the time of this life in return for the religion. These will become the followers of the blind Dajjal.
(ad-Daylami)

In the End Times of the community of the faithful, people, those who adorn the mosques but leave their own hearts in ruins, who fail to look after their religion as much as they do their clothes, who forsake their religious obligations for the sake of their activities in this world, will increase in number. (al-Hakim)
