Ruling on one who breaks the fast because he is working in intense heat
Question

                I do very hard work, working in construction in Saudi with fifteen other men. When the month of Ramadaan came, we fasted the  first and second days of Ramadaan, then they all did not fast for the rest of Ramadaan, and I did likewise, because I came from Egypt and this was the first time I experienced such weather. In the following year, I fasted Ramadaan. What is the ruling on this, knowing that when the second Ramadaan came I fasted although I had not made up the days I had missed in the previous Ramadaan. Please advise me, may Allaah reward you.
Praise be to Allah.This 
          is haraam. It is not permissible for you to do this, because fasting 
          Ramadaan is one of the five pillars of Islam. Allaah says (interpretation 
          of the meaning):
“O 
          you who believe! Observing As-Sawm (the fasting) is prescribed for you 
          as it was prescribed for those before you, that you may become Al-Muttaqoon 
          (pious)” [al-Baqarah 2:183] 
What 
          excuse will you give to Allaah when you stand before Him on the Day 
          of Resurrection, when He had given you good health, yet you did not 
          obey His Commandments and  follow His aayaat? For Allaah says (interpretation 
          of the meaning):
“O 
          you who believe! Observing As-Sawm (the fasting) is prescribed for you 
          as it was prescribed for those before you, that you may become Al-Muttaqoon 
          (pious)” [al-Baqarah 2:183] 
The 
          phrase “prescribed for you” 
          means made obligatory upon you, as it was made obligatory upon those 
          who came before you, so that you may become pious. Taqwaa (piety) is 
          described as the aim of fasting, and fasting is a means of attaining 
          taqwa.  It is a sin on you for doing that, and you have to repent 
          and seek forgiveness, and regret what has happened in the past. The 
          fact that you are working is not an excuse. You could work at night, 
          or if that is not possible, you could stop working because your work 
          is not essential. You could stop working until the month is over, or 
          do some lighter work which you can do whilst fasting.  Not fasting 
          during Ramadaan because you are working is not permissible. If there 
          are days from the previous Ramadaan which you have not made up by the 
          time the next Ramadaan comes, you have to make them up and feed the 
          poor; for  each day that you missed you must give a measure (madd) 
          of wheat or half a saa’ of another staple, and you must not do something 
          like this again. Seek the forgiveness of Allaah and remember when you 
          will stand before Him and when He will call you to account. May Allaah 
          help us and you to do that which He loves and which pleases Him.  
          And 
          Allaah knows best.
