That actually sounds so aesthetically beautiful, albeit it not practical.Like everyone said, it depends on you.
You could be married with your wife and happily living in Antarctic if that gives you peace and perfect ways to practice Islam, like you both waking up and praying Tahajjud in negative degree temperature, cold and silent, if that's what you prefer [emoji14].
So you see, it depends xD.
Masha'Allah.But ya, theoretically speaking, if you live in Saudia, Makkah - Madinah and pray 5 prayers daily there, then that's something in my opinion, or as far as I am concerned, the most peaceful and best place to live in.
Not talking on anyone's behalf, but every single time I went, I just didn't want to leave... So sad I could only go for a week maximumI wish I went every year
Assalamu Alaikum
Depends what you mean by "best"..best in what?
Lastly, salaah is when you are closest to Allah, no matter where you are.
