"I heard Abu Abdullah (as), say: 'There is no believer who has a milking goat in his house except that the people of that house are sanctified and blessed. If there are two goats, they are sanctified twice each day.' A man from our companions then asked: 'How are they sanctified?' Imam (as) replied: 'It is said to them: Blessed are you, and may your food be pure and wholesome.' I said: 'What is the meaning of being sanctified?' Imam (as) said: 'It means you are purified.'"
