وَإِذَا نَوَى الْمُسَافِرُ أَنْ يُقِيمَ بِمَكَّةَ وَمِنًى خَمْسَةَ عَشَرَ يَوْمًا: لَمْ يُتِمَّ الصَّلَاةَ.
Translation: If a traveller intends an aggregate fifteen-day stay split between Makkah and Mina, full prayer does not become obligatory.
The intended stay is split between distinct localities rather than fixed in one legally qualifying place.
