Narrated Sahl:
حَدَّثَنَا قُتَيْبَةُ ، قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ ، عَنْ أَبِي حَازِمٍ ، عَنْ سَهْلٍ ، قَالَ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَى امْرَأَةٍ أَنْ مُرِي غُلاَمَكِ النَّجَّارَ يَعْمَلْ لِي أَعْوَادًا أَجْلِسُ عَلَيْهِنَّ.
Allah's Messenger (ﷺ) sent someone to a woman telling her to "Order her slave, carpenter, to prepare a wooden pulpit for him to sit on."
