Allah's Messenger (ﷺ) said, "From among all the conditions which you have to fulfill, the conditions which make it legal for you to have sexual relations (i.e. the marriage contract) have the greatest right to be fulfilled."
Sahih al-Bukhari Book 54, Hadith 10
← Previous Hadith Allah's Messenger (ﷺ) gave the land of Khaibar to the Jews on the condition that they would work on it and cultivate it and they would get half of its yield.

Sahih al-Bukhari Book 54, Hadith 9 Next Hadith → We used to work on the fields more than the other Ansar, and we used to rent the land (for the yield of a specific portion of it). But sometimes that portion or the rest of the land did not give any yield, so we were forbidden (by the Prophet (ﷺ) ) to follow such a system, but we were allowed to rent the land for money.

Sahih al-Bukhari Book 54, Hadith 11
