It is not befitting to lie for real or as a joke, and nor for any of you to promise your child something, and then not to fulfil [your promise] to him.
If I am asked about something I know about, and I don’t want to disclose it, will I be sinful if I said “I don’t know”?
I had a disagreement with a man, and we took the matter to court where he was asked to swear an oath [that he was telling the truth], but [in actual fact] he was lying. So what is the recompense for someone who swears an oath upon the Qur.aan based upon a lie?
In the presence of my friends, sisters and teachers, I swear an oath based on a lie, whilst [at the same time] in my heart I seek forgiveness from Allaah by oft-repeating al-istighfaar – without anyone knowing about it; am I still sinful for doing so?
