A group of people with most regret on the Day of Judgement are those who used to display good behaviours and claims to deceive others, but when it was time to put those words into action, they did the opposite.

The regret of those whose words and speeches and actions were different from each other, will be great. These individuals are the hypocrites of the Ummah (Islamic nation), because they used to claim for justice and did exactly the opposite. It is narrated from Imam Sadeq (AS) who said: The most regret on the Day of Judgement will be for the one who describe justice by tongue, but acts the opposite for others [1].
