I would to know if it is possible for me to pray like my would be husband who follows another religious denomination. We are trying to find a way to practise our religion in the same way, especially for our future children. Our main differences in praying are:
he doesn’t put his arms on his chest,
he doesn’t raise his finger while in "tashahhud" sitting and
he doesn’t say "amen" after al-fatihah.
In the shia beleif, doing these three things is not permitted. This would invalidate their prayer. Thus, my question is: As a sunni, is it permissible to me not to do them?
