ثُمَّ يَعُودُ إِلَى مِنًى فَيُقِيمُ بِهَا
Translation: Then he returns to Mina and stays there.
Thumma links this instruction to the preceding visitation tawaf. Yaʿūdu means to return, while yuqīmu means to remain or stay.
The stay makes it possible to perform the rites of the days following the Sacrifice. Remaining in Mina and throwing pebbles are linked but legally distinguishable acts; the following clauses define the sequence and time of stoning.
