Sahih Muslim, 509 a
sahih

Salama b. Akwa' reported:

He sought the place (in the mosque) where the copies of the Qur'an were kept and glorified Allah there, and the narrator made a mention that the Messenger of Allah (ﷺ) sought that place and that was between the pulpit and the qibla-a place where a goat could pass.

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، - وَاللَّفْظُ لاِبْنِ الْمُثَنَّى - قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ ابْنُ الْمُثَنَّى، حَدَّثَنَا حَمَّادُ بْنُ مَسْعَدَةَ، - عَنْ يَزِيدَ، - يَعْنِي ابْنَ أَبِي عُبَيْدٍ - عَنْ سَلَمَةَ، - وَهُوَ ابْنُ الأَكْوَعِ أَنَّهُ كَانَ يَتَحَرَّى مَوْضِعَ مَكَانِ الْمُصْحَفِ يُسَبِّحُ فِيهِ ‏.‏ وَذَكَرَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَتَحَرَّى ذَلِكَ الْمَكَانَ وَكَانَ بَيْنَ الْمِنْبَرِ وَالْقِبْلَةِ قَدْرُ مَمَرِّ الشَّاةِ ‏.‏
