as-Sayyid ar-Raḍī says: Herein “mirward” is a form derived from “irwād” which means to allow time, to wait for. It is an extremely eloquent and wonderful expression. It is as though Amīr al-mu’minīn, peace be upon him, has likened the period of Banū Umayyah to a limited area meant for the training of horses for racing where they are running towards the limit, so that when they reach its extremity their organization will be destroyed.
