It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the place of Masjid Nabawi was owned by Banu Najjar. There were date palm trees and graves of polytheists in it. The Noble Prophet (peace and blessings be upon him) said to them: "Set a price for this plot with me." They said: "We will not take its price." And when the Noble Prophet (peace and blessings be upon him) was constructing it, and those people were handing things to him for the construction, at that time the Noble Prophet (peace and blessings be upon him) was reciting these verses: "Behold! The real life is the life of the Hereafter, so forgive the Ansar and the Muhajirin." Before the construction of Masjid Nabawi, whenever the time for prayer would come, the Noble Prophet (peace and blessings be upon him) would perform the prayer wherever he was.
