Re: Cairo to synchronise azaan
If you don’t take it as an offense, then I would say NO. This is not the purpose of Azaan.
The purpose of Azaan is only to let you know it’s time for namaz.
As an example, see what happens in Saudia. I never heard azaan while I was in Saudi Arabia. People there believe if you have so many other ways to know the time for namaz, why would you want to hear azaan then? Azaan is given in Saudia, but only to fulfil the tradition and in a very low volume.
People there even used to laugh at the idea of loud azaan.
Again, no offense. I might be wrong.
