وَإِنْ لَمْ يَكُنْ قَدَّمَ السَّعْيَ رَمَلَ فِي هَذَا الطَّوَافِ وَسَعَى بَعْدَهُ عَلَى مَا قَدَّمْنَاهُ.
Translation: If he did not perform the saʿi earlier, he performs ramal in this tawaf and then performs saʿi after it as previously explained.
The second condition concerns a pilgrim who has not already performed Hajj saʿi. He performs the male pilgrim's ramal in the first three circuits of this tawaf, finishes all seven tawaf circuits, and then performs seven traversals of saʿi between Safa and Marwah.
The phrase ʿalā mā qaddamnāhu refers back to the method taught earlier. It neither creates extra tawaf circuits nor changes the number of saʿi traversals.
