Narrated Hujayyah bin 'Adi:
Ali said: 'A cow is for seven.' I said: And if it gives birth?' He said: 'Then slaughter its offspring with it.' I said: 'What if it is lame?' He said: 'When it has reached the place of ritual.' I said: 'What if it has a broken horn?' He said: 'There is no harm, we were ordered' - or - 'The Messenger of Allah (ﷺ) ordered us, to check the two eyes and the two ears.'
