2. Afi ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Hammad from af-Halabiy who has said the following: “I once asked abu ‘Abd Allah , about cows and camels in matters of preference for an offering. He (the Imam) said, ‘It is the dhawat al-Arham (capable of bearing young) of cattle.’ I then asked about the age. He (the Imam) said, ‘In the case of cows age does not matter for slaughtering as offering, but camels must not be less than two years old and above.’”
