In the lifetime of Messenger of Allah ﷺ the mosque was built of adobes, its roof of the leaves of date-palms and its pillars of the stems of date-palms. Abu Bakr did not alter it. ʿUmar expanded it on the same pattern as it was in the lifetime of Messenger of Allah ﷺ by using adobes, leaves of date-palms and changing the pillars into wooden ones. ʿUthman changed it by expanding it to a great extent and built its walls with engraved stones and lime and made its pillars of engraved stones and its roof of teak wood.  

أَخْبَرَهُ أَنَّ الْمَسْجِدَ كَانَ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ مَبْنِيًّا بِاللَّبِنِ وَسَقْفُهُ الْجَرِيدُ وَعُمُدُهُ خَشَبُ النَّخْلِ فَلَمْ يَزِدْ فِيهِ أَبُو بَكْرٍ شَيْئًا وَزَادَ فِيهِ عُمَرُ وَبَنَاهُ عَلَى بُنْيَانِهِ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ بِاللَّبِنِ وَالْجَرِيدِ وَأَعَادَ عُمُدَهُ خَشَبًا ثُمَّ غَيَّرَهُ عُثْمَانُ فَزَادَ فِيهِ زِيَادَةً كَثِيرَةً وَبَنَى جِدَارَهُ بِالْحِجَارَةِ الْمَنْقُوشَةِ وَالْقَصَّةِ وَجَعَلَ عُمُدَهُ مِنْ حِجَارَةٍ مَنْقُوشَةٍ وَسَقَفَهُ بِالسَّاجِ

The mosque (of the Prophet) during his lifetime was built with bricks, its roof with branches of the palm-tree, and its pillars with palm-wood, as Mujahid said: Abu Bakr did not add anything to it. But 'Umar added to it; he built as it was built during the lifetime of the Messenger of Allah ﷺ with bricks and branches, and he changed its pillars. Mujahid said: Its pillars were made of wood. 'Uthman changed it altogether with increasing addition. He built its walls with decorated stone and lime. And he built the pillars with decorated stone and its roof with teak. Mujahid said: Its roof was made of teak. Abu Dawud said: Al-Qassah means lime used as mortar. (Using translation from Abū Dāʾūd 451)
