It is flagrant daring against the Almighty Lord

False swearing is the most dangerous sort of untruth, because it is a double crime—it is flagrant daring against the Almighty Lord and a shocking crime that eradicates the rights.

The Prophet (s) said: “Beware of false swearing, for it changes countries into deserted wastelands." ( 8 )

Imam as-Sadiq (a) said: “False swearing brings poverty to the descendants." ( 9 )

Second: Perjury

Like the previous, perjury is a serious crime resulting in denial of the rights and commonness of disorder in the society.

The Prophet (a) said: “Before the perjurer finishes his false testimony in front of the judge, his place is Hell is prepared. The same thing is said about him who conceals a testimony." ( 10 )

The holy Quran, also, warned against false wording:

“Stay away from wickedness, idols, and false words. (22:30)"
