فَإِنْ كَانَ سَعَى بَيْنَ الصَّفَا وَالْمَرْوَةِ عَقِبَ طَوَافِ الْقُدُومِ لَمْ يَرْمُلْ فِي هَذَا الطَّوَافِ وَلَا سَعْيَ عَلَيْهِ.
Translation: If he already performed saʿi between Safa and Marwah after Tawaf al-Qudum, he does not perform ramal in this tawaf and no further saʿi is due from him.
The sentence gives a condition and its consequence. Condition: the pilgrim performed a valid Hajj saʿi after Tawaf al-Qudum. Consequence: no ramal in this visitation tawaf and no repeat Hajj saʿi.
Read this within the described ifrad sequence and with valid earlier performance. Do not equate every saʿi done for an ʿumrah or a different Hajj mode with this particular act. The controlling question is whether the relevant Hajj saʿi was validly completed earlier.
