Musannaf Ibn Abi Shayba 33:75

'Affan narrated to us, he said: Abu 'Awanah narrated to us, he said: Habib ibn Abi 'Amrah narrated to us, from Sa'id ibn Jubayr, from Ibn 'Abbas, who said: "Moses truly said: 'My Lord, indeed I am, for whatever good You would send down to me, in need,' and he was the most noble of His creation to Him. He was indeed in need of half a date, and hunger had indeed afflicted him until his stomach stuck to his back."
