5. Certain persons of our people have narrated from Ahmad ibn Jumhur from Muhammad ibn al-Qasim from ibn abu Ya‘fur who has said the following: “I once asked abu ‘Abd Allah , about the eggs that I may find in the wilderness and about which ones are edible. He (the Imam) said, ‘Eat whatever is of different shapes at both ends.’”
