Chapter 23: The Book of Musaqah
Abdullah b. Umar (Allah be pleased with them) reported that Allah' s Messenger (ﷺ) 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 (ﷺ).
