What should I do, as I have become accused of treachery among my people, even though I am trustworthy, and I fear that the tribulation will become widespread?

The Prophet (peace be upon him) informed that at the end of times, standards will be overturned: the liar will be believed, and the truthful one disbelieved; the treacherous will be entrusted, and the trustworthy one deemed treacherous; and the Ruwaybidha will speak, who is the insignificant or foolish man speaking on matters of public concern. If your trustworthiness is for the sake of Allah, then the accusations of people will not harm you.
