Mishkat al-Masabih, 2516

Ibn ‘Abbas said that God’s messenger appointed the following places for putting on the <i>ihram</i>:

Dhul Hulaifa for the people of Medina, al- Juhfa for the people of Syria, Qarn al-Manazil for the people of Najd, and Yalamlam for the people of the Yemen ; so these spots are for these regions and for people of other regions who come to them intending to perform the <i>hajj</i> and the<i> ‘umra</i>. The place where those who live nearer to Mecca should put on the <i>ihram</i> (The pilgrim dress) is where they live, and so on and so on up to the inhabitants of Mecca itself who put on the <i>ihram</i> in it. Bukhari and Muslim.

وَعَنِ ابْنِ عَبَّاسٍ قَالَ: وَقَّتَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِأَهْلِ الْمَدِينَةِ: ذَا الْحُلَيْفَةِ وَلِأَهْلِ الشَّامِ: الْجُحْفَةَ وَلِأَهْلِ نَجْدٍ: قَرْنَ الْمَنَازِلِ وَلِأَهْلِ الْيَمَنِ: يَلَمْلَمَ فَهُنَّ لَهُنَّ وَلِمَنْ أَتَى عَلَيْهِنَّ مِنْ غَيْرِ أَهْلِهِنَّ لِمَنْ كَانَ يُرِيدُ الْحَجَّ وَالْعُمْرَةَ فَمَنْ كَانَ دُونَهُنَّ فَمُهَلُّهُ مِنْ أَهْلِهِ وَكَذَاكَ وَكَذَاكَ حَتَّى أهل مَكَّة يهلون مِنْهَا
