Performing Fajr Salaah just before the time expires
Q: If on the prayer calendar sunrise is at 8:38, and one prays fajr and right after the taslim one looks at ones watch and sees that it is 5 seconds are left to become 8:38 i.e. it was 8:37 and 55 seconds. Is the prayer valid? The watch one wears is a Casio Waveceptor which runs always exactly with the atomic clock.
