Narrated By Tauba Al-'Anbari : Ash-'Sha'bi asked me, "Did you notice how Al-Hasan used to narrate Hadiths from the Prophets? I stayed with Ibn 'Umar for about two or one-and-half years and I did not hear him narrating anything from the Prophet except his (Hadith): He (Ibn 'Umar) said, "Some of the companions of the Prophet including Sa'd, were going to eat meat, but one of the wives of the Prophet called them, saying, 'It is the neat of a Mastigure.' The people then stopped eating it. On that Allah's Apostle said, 'Carry on eating, for it is lawful.' Or said, 'There is no harm in eating it, but it is not from my meals."
