Yahya related to me from Malik from Ziyad ibn Sad from Amr ibnMuslim that Tawus al-Yamani said, "I found some of the companions ofthe Messenger of Allah, may Allah bless him and grant him peace,saying 'Everything is by decree.' " Tawus added, "I heard Abdullah ibnUmar say that The Messenger of Allah, may Allah bless him and granthim peace. said, 'Everything is by decree - even incapacity andability,' (or 'ability and incapacity')."
