Chapter 23: The Book of Musaqah
' Abdullah b. Umar (Allah be pleased with them) reported that when Khaibar had been conquered, the Jews asked Allah' s Messenger (ﷺ) to let them continue (cultivation in those lands) on half of the share of yield in fruits and crop, whereupon Allah' s Messenger (ﷺ) said: I will allow you to continue here, so long as we would desire. The rest of the hadith is the same, but with this addition: " The fruit would be distributed equal to the half of Khaibar. And out of hall of the produce of the land, Allah' s Apostle (may peace be be upon him) got the fifth part."
