That the Messenger of Allah designated Dhul-Hulaifah as the Miqat for the people of Al-Madinah, Al-Juhfah for the people of Ash-sham and Eguypt, Dhat 'Irq fro the people of al-Iraq, and Yalamlam for the people of Yemen. (Using translation from Nasāʾī 2653)  

أَنَّ رَسُولَ اللهِ ﷺ «وَقَّتَ لِأَهْلِ الْمَدِينَةِ ذَا الْحُلَيْفَةِ وَلِأَهْلِ الشَّامِ وَمِصْرَ جُحْفَةَ وَلِأَهْلِ الْعِرَاقِ ذَاتَ عِرْقٍ وَلِأَهْلِ الْيَمَنِ يَلَمْلَمَ»
