[FONT=arial, helvetica, clean, sans-serif]No u don't have to pray in a mosque as long as you perform the 5 daily prayers, it does not matter if u pray at home, work or mosque. Of course it is better to pray at a mosque because you pray behind an Imam and you usually make du'a together after salah but it does not make u any less of a muslim as long as u do it from the heart it does not matter where.[/FONT]
[FONT=arial, helvetica, clean, sans-serif]Praying at mosque provides less distraction (T.V Being on next room) but I would expect parents especially Mom's to pray at home and take care of the children and the home. [/FONT]
