In Islam, when faced with a moral conflict between telling the truth and causing harm, one should prioritize truthfulness while also considering the principle of avoiding harm. If telling the truth would lead to significant harm, discretion may be used, and in some cases, lying is permitted to prevent greater harm. The intention behind the decision is crucial. Consulting a scholar, reflecting on the consequences, and seeking Allah’s guidance through prayer (Istikhara) are recommended steps to navigate the dilemma.
