Build of the Prophet´s Mosque

 236. Anas bin Malik narrated: the Messenger of Allah salla alayhi wa sallam came to Al-Madinah and stayed in the upper part of Al-Madinah for fourteen nights with a tribe called Banu ´Amr bin ´Auf. He then sent for the chiefs of Banu An-Najjar, and they came with swords around their necks. He said: It is as though I see the Messenger of Allah salla alayhi wa sallam on his ride with Abu Bakr behind him and the chiefs of Abnu An-Najjar around him, until he dismounted in the courtyard of Abu Ayyub. He said:

The Messenger of Allah salla alayhi wa sallam used to pray wherever the time of prayer beomes due and he prayed in the fold of goats and sheep. He then ordered a mosque to be built. He sent for the chiefs of Banu An-Najjar, and they came (to him). He (the Prophet salla alayhi wa sallam) said to them: ´´O Abnu An-Najjar, sell this (walled) piece of land of yours to me.´´ They siad: ´´No, by allah, we would not demand its price, but (reward) from Allah.´´ Anas said: There (in this land) were date-palm trees and graves of the polytheists, and ruins. The Messenger of Allah salla alayhi wa sallam ordered that the trees be cut, and the graves dug out, and the ruins should be levelled. The trees (were thus) placed in rows towards the Qiblah (as a wall) and the stones were on both side-walls of the door, and (while building the mosque) they chanted Rajz along with the Messenger of Allah salla alayhi wa sallam: ´´O Allah! there is no good but the good of the Hereafter. So help the Ansar and the Muhajir.´´
