This is the Day of ‘Arafah, when Allāh ﷻ forgives those on Ḥajj and those who are fasting at home. Out of His ﷻ mercy He ﷻ gives this to benefit our here and hereafter. Ask for forgiveness. Ask for more love for Him ﷻ, His ﷻ prophets, awliyā’ and all believers. Ask to be with Sayyidunā l-Mahdī (as).
