Sahih Bukhari Volume 9, Book 93, Hadith Number 610.

Narrated By Abu Huraira : Once the Prophet was preaching while a bedouin was sitting there. The Prophet said, “A man from among the people of Paradise will request Allah to allow him to cultivate the land Allah will say to him, ‘Haven’t you got whatever you desire?’ He will reply, ‘yes, but I like to cultivate the land (Allah will permit him and) he will sow the seeds, and within seconds the plants will grow and ripen and (the yield) will be harvested and piled in heaps like mountains. On that Allah will say (to him), “Take, here you are, O son of Adam, for nothing satisfies you.’ “On that the bedouin said, “O Allah’s Apostle! Such man must be either from Quraish or from Ansar, for they are farmers while we are not.” On that Allah’s Apostle smiled.
