A man who fasts voluntary fasts does not perform his worldly work to the best of his ability, so what is best for him?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: If my voluntary fasting prevents me from fully and properly carrying out my worldly and religious duties due to fatigue, is it better for me to continue with this type of fasting or to leave it?

Answer:
If you are in need of work, and if you are in need of work and fasting affects your work, then it is better that you do not fast, because you are in need of work for the wage and earnings, so it is better that you do not fast. But if you are not in need of work, then there is nothing wrong with it. Yes.
