10ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنْ مُعَاوِيَةَ بْنِ وَهْبٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ النَّوْمِ فِي الْمَسْجِدِ الْحَرَامِ وَمَسْجِدِ النَّبِيِّ (صلّى اللهُ عَلَيْهِ وَآلِه) قَالَ نَعَمْ فَأَيْنَ يَنَامُ النَّاسُ.

10. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from Mu‘awiyah ibn Wahab who has said the following: “I once asked abu ‘Abd Allah, Alayhi al-Salam, about sleeping in Masjid al-Haram and Masjid of the Holy prophet. He (the Imam) said, ‘Yes, they can do so, where else can people sleep?”’
