This is the verse translation, not a definition of the individual word.
Thus they defeated them by Allah’s grace, and David killed Goliath, and Allah gave him the kingdom and wisdom and taught him whatever He willed[1]. Were it not for Allah to repel some people by others, the earth would be filled with corruption, but Allah is All-Gracious to the worlds.
