Musannaf Ibn Abi Shayba 33:1

Abu Bakr narrated to us, he said: Jarir ibn Abd al-Hamid narrated to us, from Mansur, from Mujahid, from Ubayd ibn Umayr, who said: Isa ibn Maryam, peace be upon him, would not lift his lunch for his dinner, nor his dinner for his lunch. And he used to say: "Indeed, with every day is its provision." And he used to wear hair (garments), eat from the trees, and sleep wherever evening overtook him.
