In England, some people start their fast and pray Fajr at around 3am and others at around 1am. There is no real darkness during the summer months, hence they estimate. Sunrise is at 5am at the moment. What is the ruling on this?

This question is best handled by the local qualified 'ulema because they will be fully aware of the underlying issues. However, in general the time between Fajr and sunrise has been estimated to be one and half hours so praying Fajr at one when the sun rises at five would seem too early for me. It seems that those who pray at three are closer to the truth.

And Allah knows best.
