2. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Ali ibn al-Zayyat (Ali ibn Ri’ab) from Zurarah who has said the following: “I once asked abu Ja’far, ‘Alayhi al-Salam, about the eggs that I may find in the wilderness. He (the Imam) said, ‘Do not eat whatever has its both ends of the same shape and eat that which has the ends of different shapes.’”

3. It is narrated from the narrator of the previous Hadith from his father from ibn abu ‘Umayr from ‘Umar ibn ‘Udhaynah Zurarah from abu al-Khattab who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who enters the wilderness and finds different eggs which he does not know from what kind of birds they are; if it is of birds that are undesirable or of the desirable ones. He (the Imam) said, ‘There is knowledge in it which is not unclear. If you look at each egg you can find which end is the head and which end is the bottom in which case you can eat; but if you cannot distinguish the shape of one end from the other, then leave it.’”

4. Ali ibn Ibrahim has narrated from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “I once heard abu ‘Abd Allah, ‘Alayhi al-Salam, saying, ‘If both ends of an egg are not of the same shape you then can use it for food.’ He (the Imam) said, ‘If it is of the eggs of the birds of water like the eggs of chicken with one end wider, otherwise, do not use it for food.’”
