it is amsjed
sir you got this right it is very a sensitive issue
1 the prayer is like this in the holy month of ramdan.
2 in other monthes it is in out side speakers in 3 times only fajr, maghreb and ishha.
3 in ramdan above is true in addition to salat alkiaam . starts after ishha prayer and lasts for 1 hour.
4 salat altahajod in the last ten days of the holy month starts on 0100am or it varries between diffrent masjed but mostly around this time and lasta also for 1 or 1 and half hours.
i hope i answered your questions about is it normal.
safe flights
