Abandoning One’s Fast due to Difficulties

Q: I am a laborer employed at Mahshahr; I work under terrible conditions with the weather being around 45 degrees Celsius and the nature of our work being awfully heavy. Fasting under such circumstances is extremely difficult for me such that it is taking its toll on my work and there's a chance I may be sacked as a result. Please guide me as to what I ought to do.

A: Assuming fasting will cause you harm or its toleration be accompanied with extreme difficulties, breaking one’s fast is permissible; otherwise, abandoning one’s fasting due to the presence of only some (non-extreme) excuses is not permissible.
