I told a lie a while ago and now regret doing so as that person still believes what I told them. Am I still sinning? Is repenting enough to clear the lie?
1. You need to inform that person to rectify his information. f the lie caused him or any one else any harm, you need to seek pardon from them.
2. You need to seek forgiveness and repeat Esteghfaar.
3. You need to decide not to lie again.
May Allah (SWT) forgive you and all the believers and keep us always with the truthful.
Wassalam.
