حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ صَالِحِ بْنِ كَيْسَانَ، قَالَ حَدَّثَنَا نَافِعٌ، أَنَّ عَبْدَ اللَّهِ، أَخْبَرَهُ أَنَّ الْمَسْجِدَ كَانَ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم مَبْنِيًّا بِاللَّبِنِ، وَسَقْفُهُ الْجَرِيدُ، وَعُمُدُهُ خَشَبُ النَّخْلِ، فَلَمْ يَزِدْ فِيهِ أَبُو بَكْرٍ شَيْئًا، وَزَادَ فِيهِ عُمَرُ وَبَنَاهُ عَلَى بُنْيَانِهِ فِي عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم بِاللَّبِنِ وَالْجَرِيدِ، وَأَعَادَ عُمُدَهُ خَشَبًا، ثُمَّ غَيَّرَهُ عُثْمَانُ، فَزَادَ فِيهِ زِيَادَةً كَثِيرَةً، وَبَنَى جِدَارَهُ بِالْحِجَارَةِ الْمَنْقُوشَةِ وَالْقَصَّةِ، وَجَعَلَ عُمُدَهُ مِنْ حِجَارَةٍ مَنْقُوشَةٍ، وَسَقَفَهُ بِالسَّاجِ‏.‏

In the lifetime of Allah's Messenger (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. `Umar expanded it on the same pattern as it was in the lifetime of Allah's Messenger (ﷺ) by using adobes, leaves of date-palms and changing the pillars into wooden ones. `Uthman 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.
