Narrated Anas: The Prophet said, "O Bani Najjar! Suggest a price for your garden." Part of it was a ruin and it contained some date palms.

Narrated Anas: Prior to the construction of the mosque, the Prophet offered the prayers at sheep-folds.

Narrated Anas: The Prophet came to Medina and ordered a mosque to be built and said, "O Bani Najjar! Suggest to me the price (of your land)." They said, "We do not want its price except from Allah" (i.e. they wished for a reward from Allah for giving up their land freely). So, the Prophet ordered the graves of the pagans to be dug out and the land to be leveled, and the date-palm trees to be cut down. The cut datepalms were fixed in the direction of the Qibla of the mosque.

Narrated Anas: The Prophet said (at the time of building the Mosque), "O Ban, An-Najjar! Suggest to me a price for your garden." They replied, "We do not ask its price except from Allah."
