Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
If fasting leads to severe dehydration due to long work hours, Islamic scholars allow workers in physically demanding jobs to skip the fast and make it up later. This ruling applies to those who face extreme conditions that impact their health while fasting.
In his response to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
If you are working at a hard job and you are not able to function due to dehydration because of the prolonged hours of fasting, you are allowed to skip the fast, and make up during winter when the day hours are shorter.
Eminent scholars have ruled that people doing manual jobs or working in extreme conditions and they face the risk of dehydration, they may skip fasting and make up for it later.
