أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ بْنُ سَعْدٍ، قَالَ حَدَّثَنَا نَافِعٌ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَجُلاً، قَامَ فِي الْمَسْجِدِ فَقَالَ يَا رَسُولَ اللَّهِ مِنْ أَيْنَ تَأْمُرُنَا أَنْ نُهِلَّ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يُهِلُّ أَهْلُ الْمَدِينَةِ مِنْ ذِي الْحُلَيْفَةِ وَيُهِلُّ أَهْلُ الشَّامِ مِنَ الْجُحْفَةِ وَيُهِلُّ أَهْلُ نَجْدٍ مِنْ قَرْنٍ ‏"‏ ‏.‏ قَالَ ابْنُ عُمَرَ وَيَزْعُمُونَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ وَيُهِلُّ أَهْلُ الْيَمَنِ مِنْ يَلَمْلَمَ ‏"‏ ‏.‏ وَكَانَ ابْنُ عُمَرَ يَقُولُ لَمْ أَفْقَهْ هَذَا مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏

It was narrated from 'Abdullah bin 'Umar that a man stood up in the Masjid and said: "O Messenger of Allah, from where do you command us to enter Ihram?'' The Messenger of Allah Said: "The people of Al-Madinah should enter Ihram from Dhul-Hulaifah, the people of Ash-sham should enter Ihram from Al-Juhfah, the people of Najd should enter Ihram from Qarn.'' Ibn 'Umar said: "And they say that the Messenger of Allah said: 'the people of Yemen should enter into Ihram from Yalamlam.''' And 'Ibn 'Umar used to say: "I did not hear this from the Messenger of Allah.''' Translation Not Available
