Сахих Муслима 143a

Hudhaifa reported:The Messenger of Allah (ﷺ) narrated to us two ahadith. I have seen one (crystallized into reality), and I am waiting for the other. He told us: Trustworthiness descended in the innermost (root) of the hearts of people. Then the Qur'an was revealed and they learnt from the Qur'an and they learnt from the Sunnah. Then he (the Holy Prophet) told us about the removal of trustworthiness. He said: The man would have a wink of sleep and trustworthiness would be taken away from his heart leaving the impression of a faint mark. He would again sleep and trustworthiness would be taken away from his heart leaving an impression of a blister, as if you rolled down an ember on your foot and it was vesicled. He would see a swelling having nothing in it. He (the Holy Prophet) then took up a pebble and rolled it down over his foot and (said): The people would enter into transactions amongst one another and hardly a person would be left who would return (things) entrusted to him. (And there would be so much paucity of honest persons) till it would be said: There in such a such tribe is a trustworthy man. And they would also say about a person: How prudent he is, how broad-minded he is and how intelligent he is, whereas in his heart there would not be faith even to the weight of a mustard seed. I have passed through a time in which I did not care with whom amongst you I entered into a transaction, for if he were a Muslim his faith would compel him to discharge his obligations to me and it he were a Christian or a Jew, the ruler would compel him to discharge his obligations to me. But today I would not enter into a transaction with you except so and so
