In my home mosque they pray fajr at 6:45 while the time of fajr adhan in my area of a salafiya mosque as they say starts at 6:50 and they start praying at 7:05 the reason i dont go there is because i have to drive for that and for my home mosque not. Is always like this, can i pray in my home mosque

Ustadh AbdulAziz al-Haqqan

No, if they pray before the time the salah is invalid that is if this is truly the case.
