There, the (only) protection comes from Allah, the True One. He is the Best to reward, and the Best to give success. Al-Kahf 18:44 ⧉
Tafsir:
An individual may invest his money in a venture and also apply his talents to it, hoping that his investment and his talents will lead to a successful result and will bring him good returns. But, different types of untoward incidents occur and his hopes are dashed to pieces. No human device or human talent is able to save him. In this world, time and time again God creates such situations, so that people should learn a lesson from them and should not commit the mistake of giving importance to anything except God.
