The ruling on indicating with the head or hand when greeting during prayer
Machine translationRead the Arabic original
The questioner:
If I am praying a voluntary prayer and a person passes by me and asks me a question while I am in prayer, and I indicate to him with my head, is my action permissible, or does it invalidate the prayer?
The Shaykh:
No, it does not invalidate the prayer. Merely indicating with the head or the hand does not invalidate the prayer. Yes.
The presenter:
Please, go ahead.
The Shaykh:
(peace and blessings be upon him) would return their greetings with a gesture of his hand when they greeted him while he was in prayer. Yes.
