Chapter: The mosques which are on the way to Al-Madina and the places where the Prophet (pbuh) had offered Salat (Prayers)
Abdullah told him that the Prophet (ﷺ) faced the two openings of the mountain which lay between him and the long mountain, in the direction of the Kaba. He left the mosque which was built there later on his left, at the edge of the hillock. The place where the Prophet (ﷺ) offered the prayer was below it, on the black hillock. One should leave about ten cubits from the hillock and then offer the prayer facing the two openings of the mountain situated between oneself and the Ka'ba.

وَأَنَّ عَبْدَ اللَّهِ حَدَّثَهُ أَنَّ النَّبِيَّ صلى الله عليه وسلم اسْتَقْبَلَ فُرْضَتَىِ الْجَبَلِ الَّذِي بَيْنَهُ وَبَيْنَ الْجَبَلِ الطَّوِيلِ نَحْوَ الْكَعْبَةِ، فَجَعَلَ الْمَسْجِدَ الَّذِي بُنِيَ ثَمَّ يَسَارَ الْمَسْجِدِ بِطَرَفِ الأَكَمَةِ، وَمُصَلَّى النَّبِيِّ صلى الله عليه وسلم أَسْفَلَ مِنْهُ عَلَى الأَكَمَةِ السَّوْدَاءِ، تَدَعُ مِنَ الأَكَمَةِ عَشَرَةَ أَذْرُعٍ أَوْ نَحْوَهَا، ثُمَّ تُصَلِّي مُسْتَقْبِلَ الْفُرْضَتَيْنِ مِنَ الْجَبَلِ الَّذِي بَيْنَكَ وَبَيْنَ الْكَعْبَةِ.
