The Prophet ﷺ said, "Those who act justly will be with Allah Most High upon pulpits of light at the right hand of the Most Merciful, those who are just in their judgments, with their families, and in whatever is entrusted to them."Muhammad added in his version, "And both of His hands are right hands."
