Abu Hurairah (May Allah be pleased with him) reported

Once the Prophet (ﷺ) was speaking to us when, a bedouin came and asked him: "When will the Last Day be?" The Messenger of Allah (ﷺ) continued his talk. Some of those present thought that he had heard him but disliked the interruption and the other said that he had not hear him. When the Messenger of Allah (ﷺ) concluded his speech he asked, "Where is the one who inquired about the Last Day?" The man replied: "Here I am." The Messenger of Allah (ﷺ) replied, "When the practice of honouring a trust is lost, expect the Last Day." He asked: "How could it be lost?" He replied, "When the government is entrusted to the undeserving people, then wait for the Last Day."
