Chapter 165 | Staying in ‘Arafat and Its Boundaries
11ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ سَمَاعَةَ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) إِذَا ضَاقَتْ عَرَفَةُ كَيْفَ يَصْنَعُونَ قَالَ يَرْتَفِعُونَ إِلَى الْجَبَلِ.
11. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from Sama‘ah who has said the following: “I once asked abu ‘Abd Allah , ‘What should people do if ‘Arafat becomes full?’ He (the Imam) said, ‘They can go higher toward the hills.’” NOTE: (Fatwa best explains Hadith 11 of this Chapter)
