The questioner:
Yes. Honorable Shaykh, may Allah grant you success, some Muslims do not move their lips in their recitation and dhikr during their prayer. Is their prayer considered valid?
The Shaykh:
And what makes you know about it? If this is the case, that he does not move his lips in reciting Surat al-Fatihah, his prayer is not valid. That is, reciting Surat al-Fatihah is a pillar of the prayer, so he must utter it, at least to the extent that he hears himself. Yes.
