Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Bukhari :: Book 5 :: Volume 59 :: Hadith 446
Some (of the Ansar) used to present date palm trees to the Prophet till Banu Quraiza and Banu An-Nadir were conquered (then he returned to the people their date palms). My people ordered me to ask the Prophet to return some or all the date palms they had given to him, but the Prophet had given those trees to Um Aiman. On that, Um Aiman came and put the garment around my neck and said, "No, by Him except Whom none has the right to be worshipped, he will not return those trees to you as he (i.e. the Prophet ) has given them to me." The Prophet go said (to her), "Return those trees and I will give you so much (instead of them)." But she kept on refusing, saying, "No, by Allah," till he gave her ten times the number of her date palms.
