Some men came to Sahl bin Saʿd to ask him about the pulpit. He replied, "Messenger of Allah 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 Messenger of Allah ﷺ . Messenger of Allah ﷺ ordered it to be placed in the mosque: so, it was put and he sat on it.  

بَعَثَ رَسُولُ اللَّهِ ﷺ إِلَى فُلاَنَةَ امْرَأَةٍ قَدْ سَمَّاهَا سَهْلٌ أَنْ مُرِي غُلاَمَكِ النَّجَّارَ يَعْمَلُ لِي أَعْوَادًا أَجْلِسُ عَلَيْهِنَّ إِذَا كَلَّمْتُ النَّاسَ فَأَمَرَتْهُ يَعْمَلُهَا مِنْ طَرْفَاءِ الْغَابَةِ ثُمَّ جَاءَ بِهَا فَأَرْسَلَتْ إِلَى رَسُولِ اللَّهِ ﷺ بِهَا فَأَمَرَ بِهَا فَوُضِعَتْ فَجَلَسَ عَلَيْهِ
