Sahih al-Bukhari 491
صحيح البخاري#491Sahihوَأَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ حَدَّثَهُ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَنْزِلُ بِذِي طُوًى وَيَبِيتُ حَتَّى يُصْبِحَ، يُصَلِّي الصُّبْحَ حِينَ يَقْدَمُ مَكَّةَ، وَمُصَلَّى رَسُولِ اللَّهِ صلى الله عليه وسلم ذَلِكَ عَلَى أَكَمَةٍ غَلِيظَةٍ، لَيْسَ فِي الْمَسْجِدِ الَّذِي بُنِيَ ثَمَّ، وَلَكِنْ أَسْفَلَ مِنْ ذَلِكَ عَلَى أَكَمَةٍ غَلِيظَةٍ.
