Ramadhaan & Fasting

19 hour fast

Q: We live in a small northern town in Canada . We are fasting for 19 hours a day. This is causing undue hardship on us as the long days during summer are combined with a lack of sleep. Esha is at 12pm. We are concerned about dehydration and experience extreme exhaustion . Is there a fatwa which exempts such long hours of Fasting? Could we follow the fasting hours of Mecca?

Taking sublingual tablets to quit drugs

Q: I would like to ask a question regarding Fasting (Sawm) and taking a sublingual tablets to quit drugs. The question is as follows:

May I fast if I take a sublingual tablet in the morning after suhur? The sublingual tablets name is Subutex 2mg it reduces cravings for opium
users. I would really like to fast. I would just like to know if is permissible for me for I only need to take this tablet for 7 consecutive days.

Sunnah I'tikaaf

Q: I have a question about i'tikaf. If we start itikaf on the night of the 21st there is a risk that we only complete nine nights (if Ramadan turns out to be 29 days). Will the sunnah still be fulfilled in this case? Or should we start the itikaf at the night of the 20th in order to make sure that we do at least 10 nights?
