Musnad Ahmad 25:91

Sufyan narrated to us, from ‘Amr, from Tawus, who said: I heard Ibn ‘Abbas say: "As for that which the Messenger of Allah (ﷺ) forbade—that it be sold until it is taken possession of—it is food." And Ibn ‘Abbas said, based on his own opinion: "And I do not consider everything else to be anything but like it."
