Allah does not guide a transgressing liar

Untruth denotes the disconformity of speech with reality. It is surely the source of evils. From this cause, the Islamic Sharia has banned untruth, censured the untruthful, and threatened them through numerous texts in the Quran and Sunna:

“Allah does not guide a transgressing liar. (40:28)"

“Woe to every sinful liar! (45:7)"

“Those who do not believe in the miracles of Allah invent lies and they are liars. (16:105)"

In the Farewell Pilgrimage ( 1 ) , the Prophet (s) said: “Forging lies against me has been common to a great extent. However, it will increase. He who forges lies against me intentionally should find himself a place in Hell. When you receive any hadith, you sh ould first measure it according to the criteria of the Quran and my Sunna. If it conforms to them, you will then adopt it. If not, you should then throw it away." ( 2 )

Amir ul-Mu'minin (a) said: “Persistence on telling untruths brings about poverty." ( 3 )

Imam al-Baqir (a) said: “Allah has made locks for the evil and made drinking wine the master key of all these evils. Untruth, in fact, is eviler than drinking wines." ( 4 )

“Telling untruths is the destruction of faith." ( 5 )

“Ali ibn al-Hussein (a) used to say to his sons: Avoid telling untruths, whether they were significant or venial, or in serious or humorous situations, for a man who tells a trivial lie will surely dare to tell a big one. Know that the Prophet (s) said:

A servant persists on telling only the truth until Allah records him as truthful. The teller of lies, on the other side, keeps on telling untruths until he is recorded with Allah as liar." ( 6 )

Jesus (a) said: “He who tells very much untruth will lose brightness." ( 7 )a
