Seeking Allah's Mercy
Qul HuwaAllahu Ahud!

Jazakallahkhair sister for your concern, But I've found fatwas related to the issue. I think you should read all that are posted above by me. You need to correct your ideas Inshaa'Allaah.
:salam2: sister,Sister, I would like to let you know that the concept of Imsak isn't correct as we've been told to eat until the Fajr athan. Imsak is 10 minutes before the fajr athan, so why would we stop 10 minutes early??
Secondly, we're not supposed to 'say' our intention to fast. This was being discussed only yesterday here: http://www.turntoislam.com/forum/showthread.php?t=79048

As per the fatawaas above, one shouldn't really depend on the Adhan itself. The 'actual' time is the breaking of dawn, and the Adhan is dependant on timetables are more than often wrong. But according to Sheikh Uthymin and many others, since we cannot identify the breaking of dawn in cities due to lights and all, there is not harm in following the Adhan i.e starting the fast when the Muezzin gives the adhan.
jazakallah khair for correcting sister Queenislaam.
