❖ Question
Is it necessary to repeat Salah that was performed in a state of impurity (najāsah)?
❖ Answer
Al-ḥamdu lillāh, waṣ-ṣalātu was-salāmu ʿalā Rasūlillāh, ammā baʿd!
- If a person suffers from illness and does not know when exactly the impurity (najāsah) occurred, then in such a case:
✔ His Salah will be considered valid.
✔ Repetition of that Salah is not obligatory. - However, for future Salah, one must exercise due care and precaution to avoid performing prayer in such a state.
