المسجد النبوي
c. 624–628 CE (2–7 AH): after the qibla turned to Makkah, before the enlargement after Khaybar
The Prophet ﷺ built the mosque on reaching Madinah in 1 AH, on a date-drying ground that belonged to two orphans, Sahl and Suhayl; palms, a ruin and old graves were cleared, and he carried stones with his Companions. This model shows it after the qibla turned from Jerusalem to Makkah in 2 AH: walls of sun-dried mud brick on a stone footing, a shade of palm fronds on palm-trunk pillars along the qibla wall, the Suffah's shade at the back, an open court between, and the first two of his houses on the east side. There was no minbar, no mihrab and no lamp yet. The size follows Kharija b. Zayd's report of 70 by 60 cubits (about 34 × 29 m); other reports give 54⅔ by 63 cubits or less than 100 by 100. The number of pillars, the wall height and the sizes of the rooms are not recorded, so those are estimates.
