Final answer:
Abu Bakr should be chosen for the role based on historical context and the provided information.
Step-by-step explanation:
The question at hand revolves around the choice between Sharif-ul-Hashim and Abu Bakr for a particular role. To answer this, we need to provide some relevant historical context. After the death of the Prophet Muhammad, there was a dispute over leadership in the Muslim community. Abu Bakr was ultimately chosen as the first successor to Muhammad, becoming the caliph or religious and political leader. This decision was made through popular acclamation by tribal leaders. On the other hand, Sharif-ul-Hashim is not specifically mentioned in the provided information. Therefore, based on the given information, Abu Bakr should be chosen for the role.
