Sahih al-Bukhari 2094
Narrated Abu Hazim:
Some men came to Sahl bin Sa`d to ask him about the pulpit. He replied, "Allah's Messenger (ﷺ) sent for a 
woman (Sahl named her) (this message): 'Order your slave carpenter to make pieces of wood (i.e. a 
pulpit) for me so that I may sit on it while addressing the people.' So, she ordered him to make it from 
the tamarisk of the forest. He brought it to her and she sent it to Allah's Messenger (ﷺ) . Allah's Messenger (ﷺ) 
ordered it to be placed in the mosque: so, it was put and he sat on it.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، عَنْ أَبِي حَازِمٍ، قَالَ أَتَى رِجَالٌ إِلَى سَهْلِ بْنِ سَعْدٍ يَسْأَلُونَهُ عَنِ الْمِنْبَرِ، فَقَالَ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَى فُلاَنَةَ ـ امْرَأَةٍ قَدْ سَمَّاهَا سَهْلٌ ـ ‏
"‏ أَنْ مُرِي غُلاَمَكِ النَّجَّارَ، يَعْمَلُ لِي أَعْوَادًا أَجْلِسُ عَلَيْهِنَّ إِذَا كَلَّمْتُ النَّاسَ ‏"‏‏.‏ فَأَمَرَتْهُ يَعْمَلُهَا مِنْ طَرْفَاءِ الْغَابَةِ ثُمَّ جَاءَ بِهَا، فَأَرْسَلَتْ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم بِهَا، فَأَمَرَ بِهَا فَوُضِعَتْ، فَجَلَسَ عَلَيْهِ‏.‏
