HAHAHAHAHAHAHA
Actually its daylight Savings in Australia so we pray Fajr at 5:00.. I couldnt fool her.. she always keeps her mobile under her pillow.. she sets the alarm and if i played the athan she would have known the time as she would quickly check her mobile..
Also she would know its not the Athan for fajr prayer.. because it would sound different to the one that we already play for every prayer.. our Athan software has a different voice... And also she wanted to get some sleep because she had a job interview.. I hope it goes well for her..
I will listen to it now as it is day..

Your Post really made me laugh though.. Thanks..
