وَلِلَّهِ غَيْبُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَإِلَيْهِ يُرْجَعُ ٱلْأَمْرُ كُلُّهُۥ فَٱعْبُدْهُ وَتَوَكَّلْ عَلَيْهِ ۚ وَمَا رَبُّكَ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ
And Allah's is the Invisible of the heavens and the earth, and unto Him the whole matter will be returned. So worship Him and put thy trust in Him. Lo! thy Lord is not unaware of what ye (mortals) do.

Sahih al-Bukhari
Hajj (Pilgrimage)
Chapter: The Miqat for the people living within Mawaqit
Narrated Ibn `Abbas:
The Prophet (ﷺ) fixed Dhul-Hulaifa as the Miqat for the people of Medina, Al-Juhfa, for the people of Sham, Yalamlam for the people of Yemen, and Qarn for the people of Najd. And these Mawaqit are for those living at those very places, and besides them for those who come through those places with the intention of performing Hajj and Umra; and whoever is living inside these places can assume lhram from his own dwelling place, and the people of Mecca can assume lhram from Mecca.
