Fasting

Yes, you have to do that.

This is up to you. It is best for you to fast but you have the permission not to. http://islamqa.info/en/cat/107

Wa alaikum salam, As long as you have break of dawn and sunset, you must fast accordingly!

Wa alaikum salam, As long as you have spitted the water, this is sufficient. Whatever remains in the mouth is negligible.

Wa alaikum salam wa rahmatullaahi, You have to see a muslim doctor. If he tells you not to fast, you must not fast. If he tells you that this will be cured later,you must make these days when you are better. But if he says that you will  never ever be able to fast again, you must feed […]

Assalamu alaikum, Your fast is valid as the intention was made correctly before athan and y didn’t nullify it.

Assalamu alaikum, If the medication is truly this needed to be taken in such interval, this is permissible. However, I very much doubt that you can’t take it at sunset and before the break of dawn only in Ramadan. Check with another doctor.

Wa alaikum salam, yes you can. No problem.

Wa alaikum salam, The fasting is valid.
