Al-Allaamah Ash-Shaykh Ahmad An-Najmee – Rahimahullah – was asked:
Is there an old Salafiyyah and a new Salafiyyah or is it one Salafiyyah?
As-Salafiyyah is one Salafiyyah, and whomsoever claims that there is an old Salafiyyah and a new Salafiyyah has indeed lied. When we contemplate on the Aqeedah of the Salaf from the time of the companions until our time, we find it is one Aqeedah. They did not differ regarding it. And if they did differ it was in the subsidiary rulings which are not from the foundations (usool) and not from the Aqeedah, they differed in this (subsidiary rulings) whilst not one of them censured the other (due to the differing in subsidiary issues).
This is the path of the companions – May the pleasure of Allah the Most High be upon them.
As for the Aqeedah, the methodology with regards to it is one, from the time of the Sahaabah until now.
