What are the educational and da'wah dimensions of the the Day of 'Arafah, and are there available references on these topics?

The Day of Arafat, as Imam Al-Ghazali mentioned, reveals many educational, da'wah-related, and ethical secrets and objectives. On this day, the pilgrim recalls the plains of resurrection and the gathering of nations. A Muslim benefits from this day in several ways, including: disciplining the self through dhikr and supplication, feeling the unity of Muslims and their equality before Allah, realizing their mutual need for one another, achieving harmony and familiarity, exchanging knowledge and ethics, learning about the conditions of Muslims, remembering the Greatest Standing before Allah, and surrendering completely to Allah's commands.
