What is the time for my 'Isha and Fajr prayers in the city of Antwerp, Belgium, given that they occur at the same time (1:46) between late May and mid-July, and that the night is not completely dark after sunset during that period?

The time for the Isha prayer begins with the disappearance of the red twilight. Muslims are required to perform each prayer at its prescribed legal time as long as the legal sign is clear. Similarly, the time for abstaining from food in fasting (imsak) is observed with the appearance of dawn. The closeness of the Isha and Fajr entry times, or the absence of deep darkness at night, does not affect this, as what is considered is the sunset for the end of the day, and the appearance of true dawn (Al-Fajr Al-Sadiq) for the end of the night.
