In making salah,do you combine Fardh and Sunnah rakahs??
Or you do one(fardh)or the other(sunnah)?
Also, to become a Muslim,is it necessary to declare that you are a Muslim in the company
of two other Muslims?
thank you

al-hamdu lillaah.

Fardh and sunnah prayers have to be performed
separately.

You don’t need witnesses to become a
Muslim. Once you utter the Shahadatain believing in them, you are then a
Muslim.

Islam & Related Issues “.
