Sunan Ibn Majah Book 5, Hadith 1416

حَدَّثَنَا أَحْمَدُ بْنُ ثَابِتٍ الْجَحْدَرِيُّ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي حَازِمٍ، قَالَ اخْتَلَفَ النَّاسُ فِي مِنْبَرِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ مِنْ أَىِّ شَىْءٍ هُوَ فَأَتَوْا سَهْلَ بْنَ سَعْدٍ فَسَأَلُوهُ فَقَالَ مَا بَقِيَ أَحَدٌ مِنَ النَّاسِ أَعْلَمَ بِهِ مِنِّي هُوَ مِنْ أَثْلِ الْغَابَةِ عَمِلَهُ فُلاَنٌ مَوْلَى فُلاَنَةَ نَجَّارٌ فَجَاءَ بِهِ فَقَامَ عَلَيْهِ حِينَ وُضِعَ فَاسْتَقْبَلَ الْقِبْلَةَ وَقَامَ النَّاسُ خَلْفَهُ فَقَرَأَ ثُمَّ رَكَعَ ثُمَّ رَفَعَ رَأْسَهُ فَرَجَعَ الْقَهْقَرَى حَتَّى سَجَدَ بِالأَرْضِ ثُمَّ عَادَ إِلَى الْمِنْبَرِ فَقَرَأَ ثُمَّ رَكَعَ فَقَامَ ثُمَّ رَجَعَ الْقَهْقَرَى حَتَّى سَجَدَ بِالأَرْضِ ‏.‏

It was narrated that Abu Hazim said:“The people differed concerning the pulpit of the Messenger of Allah (ﷺ) and what it was made of. So they came to Sahl bin Sa’d and asked him. He said: ‘There is no one left who knows more about that than I. It is made of tamarisk (a type of tree) from Ghabah. It was made by so-and-so, the freed slave of so- and-so (a woman), (who was) a carpenter. He brought it and he (the Prophet (ﷺ)) stood on it when it was put in position. He faced the Qiblah and the people stood behind him. He recited Qur’an, then bowed and raised his head, then he moved backwards until he prostrated on the ground, then he went back to the pulpit and recited Qur’an, then bowed and raised his head, then he moved backwards until he prostrated on the ground.”
