2 – The ḥadith establishes that reciting al-Fātiḥah in the prayer is obligatory and that it is a pillar without which the prayer is invalid. The soundest opinion is that it is required in every single rakʿah, based on the ḥadith of the man who prayed incorrectly: “Then do that throughout your entire prayer.” Narrated by al-Bukhārī (724) and Muslim (397).
3 – “No prayer…” The negative particle lā serves to negate the very essence of a thing; that is its primary function. It only negates qualities when negating the essence is impossible.
