Sahih Muslim 509 b
Yazid reported:
Salama sought to say prayer near the pillar which was by that place where copies of the Qur'an were kept. I said to him: Abu Muslim. I see you striving to offer your prayer by this pillar. He said: I saw the Messenger of Allah (ﷺ) seeking to pray by its side.
حَدَّثَنَاهُ مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مَكِّيٌّ، قَالَ يَزِيدُ أَخْبَرَنَا قَالَ كَانَ سَلَمَةُ يَتَحَرَّى الصَّلاَةَ عِنْدَ الأُسْطُوَانَةِ الَّتِي عِنْدَ الْمُصْحَفِ فَقُلْتُ لَهُ يَا أَبَا مُسْلِمٍ أَرَاكَ تَتَحَرَّى الصَّلاَةَ عِنْدَ هَذِهِ الأُسْطُوَانَةِ ‏.‏ قَالَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يَتَحَرَّى الصَّلاَةَ عِنْدَهَا ‏.‏
