The Book of Transactions (Kitab Al-Buyu`)

Muslim :: Book 10 : Hadith 3762

Abdullah b. Umar (Allah be pleased with them) reported that Allah's Messenger (may peace be upon him) returned to the Jews of Khaibar the date-palms of Khaibar and its land on the condition that they should work upon them with their own wealth (seeds, implements), and give half of the yield to Allah's Messenger (may peace be upon him).
