AVAudioPlayer stop a sound and play it from the beginning

I used the AVAudioPlayer to play a 10 sec wav file and it works fine. Now I what to stop the wav at the 4th sec and then play it again from the very 1st sec.

Here is the code I tried:

NSString *ahhhPath = [[NSBundle mainBundle] pathForResource:@"Ahhh" ofType:@"wav"];
AVAudioPlayer *ahhhhhSound =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:ahhhPath] error:NULL];

[ahhhhhSound stop];
[ahhhhhSound play];

What I get is, the wav stops at the 4th sec but when I run the [XXX play] again, the wav continues to play the 5th sec instead of playing from the beginning.

How could I get this done? Any help will be appreciated.
