Maliks Muwatta Book 34, Hadith Number 3.

Malik related to me from Ibn Shihab that he asked Salim ibn ‘Abdullah ibn Umar about renting out fields. He said, “There is no harm in it for gold or silver.” Ibn Shihab said, “I said to him, ‘What do you think of the hadith which is mentioned from Rafi ibn Khadij?'” He said, “Rafi has exaggerated. If I had a field, I would rent it out.”
