Q 4: Is it permissible for a person to lie in their dealings with other people? For example, it is known that an airline ticket between
costs 240 riyals, but a person may claim that
thousand riyals to pay 240 riyals for the ticket and take the rest for themselves. Is this deceptive dealing permissible between Muslims?
It is Haram (prohibited) to
tell lies except in certain cases. Allah (Exalted be He) says,
O you who believe! Be afraid of Allâh, and be with those who are true (in words and deeds).
(Part No. 26; Page No. 53) Since lying as mentioned in the question serves no Maslahah (public interest), then it is Haram. Also, the excess money taken is Haram and should be returned to its owners.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
