Yahya related to me from Malik, from Ibn Shihab, that Salim ibn
Abdullah heard Abu Hurayra relating to Abdullah ibn Umar how a group
of three people in ihram had passed him at ar-Rabadha and had asked
him for a fatwa about eating game which people who were not in ihram
were eating, and he told them that they could eat it. He said, "Then I
went to Umar ibn al-Khattab in Madina and asked him about it, and he
said, 'What did you say to them?' and I said, 'I told them that they
could eat it.' Umar said, 'If you had told them anything else I would
have done you an injury.' "
