Praise be to Allaah.
So long as you are going to
take the coastal route, then your meeqaat is Yalamlam, the meeqaat of the
people of Yemen, because the Prophet (peace and blessings of Allaah be
upon him) designated Yalamlam as the meeqaat for the people of Yemen, then
after mentioning the meeqaats he said: “And these
meeqaats are for the people at those very places, and besides them
for those who come thorough those places with the intention of performing
Hajj and 'Umrah” Narrated by al-Bukhaari (1524) and Muslim (1181).
This is your original
meeqaat; as for the meeqaat of al-Sayl al-Kabeer, you should enter ihraam
from it if you come to Makkah via al-Taa’if.
And Allaah knows best.
