Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, "When the trust is lost, then wait for the Hour." It was said, "O Messenger of Allah, how will it be lost?" The Prophet said, "When authority is given to those who do not deserve it, then wait for the Hour." Source: Sahih Bukhari 6131
How is trust being lost related to the last hour and the day of judgement? Before the day of judgement, the system of the planets, stars and galaxies will be in chaos and everything will fall apart. Similarly, when the trust between people is lost, the balance in society falls apart. Be a trustworthy person to your family, friends and community in general.
"Those who respect their trusts and covenants; and those who stand firm in their testimonies; and those who guard (the sacredness) of their worship; such will be the honored ones in the Gardens (of Bliss)" (70:32-34)
