Descripción:

Following Ali's murder, Hasan ibn Ali attained to the caliphate. To avoid the agonies of a further civil war, Hasan signed the Hasan–Muawiya treaty with Muawiyah. According to the treaty, Hasan ceded the caliphate to Muawiyah but the latter could name no successor during his reign; instead, he was to let the Islamic world choose its successor afterward.
