This page attempts to enlist Expansion Chronology of Masjid al-Nabawi
circa 622 CE
A model of the original mosque, at Dar al Medina, built by prophet Muhammad after he arrived in Medina following Hejrah from Mecca. The original mosque was 35 meters long and 30 meters wide. The imagined layout of the mosque as it might have looked in the first year of Hijrah, back then it was oriented north-south. The qiblah wall was to the north towards al-Aqsa and the al-Suffah was along the south wall.
circa 629 CE
First expansion of Masjid al-Nabawi took place right after the Battle of Khaybar, Width was increased by 20 meters and the length by 15 meters. The new dimensions became 50×50 meters. The northern boundary of the Mosque was where the Turkish construction ends in this direction. On the west side its boundary was five columns west of the pulpit. You will see written on each column there ‘The boundary of Prophet’s Mosque.’ The foundation was laid with stones and the walls were built of unbaked mud bricks like before. The columns were made of palm tree and the roof was covered by branches of palm trees. The height of the roof was increased from 2½ meters to 3½ meters. Caliph Osman paid for the land for this addition of the mosque.
circa 639 CE
People requested the Caliph to extend the mosque since the population of muslims increased considerably. In 17Hj. Umar al-Khattab extended the mosque by five meters to the south, 15 meters to the north and 10 meters to the west. New dimensions of mosque thus became 70×60 meters. The western boundary of the mosque was upto seventh column from the pulpit. The roof was raised to 5½ meters. In the western wall a new door was added, called Bab Salam. Similarly a door was added in the eastern wall, called Bab Nisa. Omar ibn al-Khattab also made a platform on the eastern side of the mosque by the side of the house of Khaled bin Waleed. Since it is not permitted to gossip or raise voice in a mosque, caliph Umar said, “Those who want to engage themselves in gossip or recite poetry may use this platform.”
circa 653 CE
In 29 Hj. Usman ibn Affan further extended the mosque by about 5 meters to south, by about 5 meters to north and by about 5 meters westwards. Hence the mosque was extended upto eight columns westward from the pulpit. It is interesting to note that the southern wall of the mosque is still at the same place today and no extension was ever made in this direction since the time of Caliph Osman. The building was constructed with decorative stones and lime mortar was used as construction material. The roof was made of teak wood. The columns were also made of decorative stones and were hollow inside. Iron bars and molten lead was put inside the columns to reinforce them. Caliph Osman supervised the construction activities personally. He made a protective enclosure around the area where he led the salat to avoid attack on him during the salat. This enclosure had windows and people could see the Imam through these windows. At present the Imam leads the salat from the same spot where Usman ibn Affan did. There is no protective enclosure nowadays. However, the security personnel are posted there before, during and after the salat to avoid any mishap.
circa 712 CE
In 88 Hj. Waleed bin Abdul Malik ordered the Governor of Madina, Omar bin Abdul Aziz to extend the mosque further. Omar bin Abdul Aziz extended it about ten meters to the west and about fifteen meters to the east. It is necessary to mention here that by this time all the wives of the Prophet had passed away. Omar bin Abdul Aziz purchased their Hujrats (huts) from their relatives and included this area in the mosque. Aisha’s hujra was left as it was because of the graves in it. The building and the columns were reinforced with iron bars and molten lead. The roof was made of teakwood and was raised to a height of 12.5 meters. This lower roof was covered by another roof to protect against severe weather. Marble slabs were fixed on the inner side of walls. These walls also had multicolored stones and gold polish put on them at different spots. Gold polish was also put on the frames of the doors. Omar bin Abdul Aziz personally supervised the construction. He was the one who built four minarets on the four corners of the mosque and the new mosque had twenty doors. These construction activities took three years from 88 Hj. through 91 Hj.
