Musannaf Ibn Abi Shayba 13:347

Ibn Abi Za'idah narrated to us, from Muhammad ibn Ishaq, from 'Amr ibn Shu'ayb, from his father, from his grandfather, who said: I heard a man from Muzaynah asking the Prophet, peace and blessings of Allah be upon him, about fruits while they were still in their coverings (calyxes). He said: "Whoever eats with his mouth and does not take [in his garment/lap], there is nothing upon him."
