Musnad Ahmad 1153:1288

Muhammad ibn Bakr narrated to us, Ibn Jurayj informed us, from Ibn Shihab, that it reached him from him, from ‘Urwah, from ‘Aishah, that she said while mentioning the affair of Khaybar: Then he mentioned the hadith, except that he said: "When the first of the dates ripen." And he said: "Before the fruits are eaten."
