Telling a lie as an evil characteristic, and also liars are seriously rejected by God in the Koran:
1. Those who do not believe in Gods signs are merely inventing a lie, such men are liars.(16:105)
2. A man from pharaohs’ court who was a believer and been hiding his faith said: “what will you kill a man for merely saying: My Lord is God? He has brought you explanations about your Lord . If he is a liar, then lie falls upon himself, while if he if truthful, some of what he threatens you with afflict you. God does not guide anyone who is a preposterous liar. (40:28)
3. So he [God] planted hypocrisy in their till the day when they will meet him because they broke their word to God which they had promised him and for how they had been lying.(9:77)
4. Pure religion belongs to God [Alone]! The ones who take on [other] patrons instead of him [claim]:” we do not serve them except to bring us closer to God in homage. “God will judge among about whatever they have been differing over, God does not guide anyone who is a disbelieving liar (39:3)
5. Their hearts contain malice so God has increased their [share of] malice.
They will have painful torment because they have been lying.(2:10)
