Notes (Tafseer)

502. The full meaning of Sabr is to be understood here, viz.: Patience, perseverance, constancy, self-restraint, refusing to be cowed down. These virtues we are to exercise for ourselves and in relation to others; we are to set an example, so that others may vie with us, and we are to vie with them, lest we fall short; in this way we strengthen each other and bind our mutual relations closer, in our common service to Allah.

503. Prosperity (falah here and in other passages is to be understood in a wide sense, including prosperity in our mundane affairs as well as in spiritual progress. In both cases it implies happiness and the attainment of our wishes, purified by the love of Allah.
