What is the legitimate time for the 'Isha prayer in Birmingham, UK, during the summer, given the long period between the Maghrib and 'Isha calls to prayer?

First: One must adhere to the prescribed prayer times if night and day occur within twenty-four hours, even if one is long or short, based on the Almighty's saying: (Indeed, performing prayers is a duty on the believers at fixed times).

Second: Countries where night and day do not occur within twenty-four hours should estimate their prayer times based on the nearest country to them where night and day do occur, and their prayer times should be estimated as twenty-four hours, as in the hadith (definition) of the Dajjal: (Estimate for it its measure).

Third: Countries where the twilight connects with dawn, or where it disappears and there is not enough time for the 'Isha prayer, should estimate their times based on the nearest place to them where there is sufficient time for the prayers.

Fourth: It is permissible for those with excuses to combine the Maghrib and 'Isha prayers by advancing them if waiting for the 'Isha time would cause them hardship, and the estimation of hardship is referred to custom.

Fifth: Estimating the time between Maghrib and 'Isha as one hour and 32 minutes was not reported from Sheikh Al-Uthaymeen; rather, it varies according to seasons and locations.
