Hisham said: And Yahya wrote to me, from Ya'la ibn Hakim, from Sa'id ibn Jubayr, from Ibn Abbas, "He used to say: In the case of the haram, there is an oath for which expiation is due." And Ibn Abbas said: "Indeed, you have in the Messenger of Allah a good example, that the Prophet, peace and blessings be upon him, had forbidden his slave girl to himself, so Allah said: 'Why do you forbid what Allah has made lawful for you' (Surat al-Tahrim, verse 1) up to His saying: 'Allah has already ordained for you the dissolution of your oaths' (Surat al-Tahrim, verse 2), so he made expiation for his oath and made the haram an oath."
