باب مَا ذَكَرَ النَّبِيُّ صلى الله عليه وسلم وَحَضَّ عَلَى اتِّفَاقِ أَهْلِ الْعِلْمِ
Sahih al-Bukhari 7344

Narrated `Abdullah bin Dinar:

Ibn `Umar said, "The Prophet (ﷺ) fixed Qarn as the Miqat (for assuming the Ihram) for the people of Najd, and Al-Juhfa for the people of Sham, and Dhul-Hulaifa for the people of Medina." Ibn `Umar added, "I heard this from the Prophet, and I have been informed that the Prophet (ﷺ) said, 'The Miqat for the Yemenites is Yalamlam.' "When Iraq was mentioned, he said, "At that time it was not a Muslim country."

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، وَقَّتَ النَّبِيُّ صلى الله عليه وسلم قَرْنًا لأَهْلِ نَجْدٍ، وَالْجُحْفَةَ لأَهْلِ الشَّأْمِ، وَذَا الْحُلَيْفَةِ لأَهْلِ الْمَدِينَةِ‏.‏ قَالَ سَمِعْتُ هَذَا مِنَ النَّبِيِّ صلى الله عليه وسلم وَبَلَغَنِي أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ وَلأَهْلِ الْيَمَنِ يَلَمْلَمُ ‏"‏‏.‏ وَذُكِرَ الْعِرَاقُ فَقَالَ لَمْ يَكُنْ عِرَاقٌ يَوْمَئِذٍ‏.‏
