I have a non muslim friend who will inshaalah convert to islam, but as he asked me what he should do, I told him that after he converts he should try to make prayer a habit. But the problem is I don't want to burden him so early on with shia sunni polemics. We have different fiqh than our sunni brothers. Also, there are certain rules for salah that need to be learnt. So what do I do, how do I tell him how to pray. Should I ask him to pray the shia way or the sunni way? And if the sunni way what madhab do I tell him. I am confused so could you grant me some guidance please.

1- Yes you are right. Don’t overburden him. Let him learn the details step by step.

2- Have him watch this prayer video (you should teach him the Shia way):

3- A month later have him watch this series:
