2ـ أَبُو عَلِيٍّ الأَشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ أَبِي أَيُّوبَ الْخَزَّازِ عَنْ أَبِي عُبَيْدَةَ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) الصَّلاةُ فِي الْحَرَمِ كُلِّهِ سَوَاءٌ فَقَالَ يَا أَبَا عُبَيْدَةَ مَا الصَّلاةُ فِي الْمَسْجِدِ الْحَرَامِ كُلِّهِ سَوَاءً فَكَيْفَ يَكُونُ فِي الْحَرَمِ كُلِّهِ سَوَاءً قُلْتُ فَأَيُّ بِقَاعِهِ أَفْضَلُ قَالَ مَا بَيْنَ الْبَابِ إِلَى الْحَجَرِ الأَسْوَدِ.

2. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya abu Ayyub al-Khazzaz from abu ‘Ubaydah who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, if performing Salat (prayer) in all of al-Haram (the sacred area) is of the same degree of virtue. He (the Imam) said, ‘O abu ‘Ubaydah, all Salat (prayer) in Masjid al-Haram are not of the same degree of virtue; then how can it be the same in all of al-Haram (the sacred area)?’ I then asked, ‘Which part of it is more excellent?’ He (the Imam) said, ‘It is between the door and the Black Stone.’”
