It was narrated from Safiyyah bint Shaimah that a woman said: I saw the Messenger of Allah hastening at the bottom of the valley and he said: "The river bed should not be crossed except with vigor". (Sahih) Chpater 178. The Place Where One Should Walk
The Prophet Muhammad's advice is applicable even today as it encourages us to remain determined and motivated when facing challenges or obstacles in life. We must remember that hard work pays off eventually if we are willing to put in the effort required for success. Furthermore, this hadith serves as an example of how one should conduct themselves when faced with difficult tasks; by being energetic and enthusiastic about what needs to be done instead of giving up easily or becoming discouraged by failure or difficulty.
