Abī l-Ḥusayn al-Kalbī (#22558); Ya'īš (#28457)}} Hasan was replaced by his son, Ahmad, who ruled Sicily until his recall to North Africa in 969, with Ya'ish replacing him.{{sfn|PmbZ|loc=Aḥmad b. al-Ḥasan b. ʻAlī al-Kalbī (#22558); Ya'īš (#20188)}} Ya'ish however proved unable to quell the factional quarrels within his province between different Berber tribes. As a result, he was replaced in June 970 by Ahmad's brother, Ali.{{sfn|PmbZ|loc=Abū l-Qāsim ʻAlī b. al-Ḥasan al-Kalbī (#20072); Ya'īš (#28457)}}
