It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that during the blessed era of the Prophet (peace and blessings be upon him), Masjid Nabawi was built of unbaked bricks, its roof was covered with branches, and its pillars were made from the wood of date-palm trees. Sayyiduna Siddiq Akbar (may Allah be pleased with him) did not make any additions to this construction during his caliphate. Sayyiduna Umar Farooq (may Allah be pleased with him) made some additions to its construction, but its foundation was based on the same structure as during the blessed era of the Prophet (peace and blessings be upon him), that is, unbaked bricks and branches, and he also had new wood installed in the pillars. Sayyiduna Uthman Ghani (may Allah be pleased with him) was the first to make changes in its structure and made many additions to it. He had its walls built with decorated stones and lime, its pillars made from decorated stones, and teak wood placed on its roof.
