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 (a.s.), 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.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (22/39))
