(5) باب إِبْطَالِ الْوَصِيَّةِ لِلْوَارِثِ
It was narrated from Shahr bin Hawshab that Ibn Ghanm mentioned that Ibn Kharijah told him that he saw the Messenger of Allah addressing the people from atop his mount, which was chewing its cud and its saliva was dripping down. The Messenger of Allah said in his Khutbah:
"Allah has given each person a share of the inheritance, and it is not permissible to give bequests to an heir."
