وَمَنْ كَرَّرَ تِلَاوَةَ سَجْدَةٍ وَاحِدَةٍ فِي مَجْلِسٍ وَاحِدٍ: أَجْزَأَتْهُ سَجْدَةٌ وَاحِدَةٌ.
Translation: Whoever repeats the same prostration verse in one sitting, one prostration suffices.
Two qualifications matter: it is the same verse, and it is one gathering. Repetition in these circumstances does not generate a separate required prostration for every recitation.
