First define secularim. I have intentionaly used the term with the modern day salaafi movment. Secularisim as far as I understand it to be in the relegious context is to seperate out relegion from the daily lives. This is exactly what most Secular Salaafist do, by focusing on some hand picked topics i.e Aqaid, concept of school of thought , usual salaat releated topics. By doing this the the relegion is inadvertantly grouped into a area disconnected from the broader aspect of life. Is this not what the irrelegious secularist want. By extenstion this Secular Salaafism is just that an 'ism' - seemingly relegious. Scholar saying this is not halal and this is haram is not a rebuttle against secularism. Imam Ashari, Matrudi, Nafasi didn't just state the creed they defended and attacked the batil. The Salaafi movment as it stands today can not stand up intelectually. What are they going to do - Quote Bukhari and Muslim as a defence or cite Imam Ibn Taimiyah (RAH) when the arguements by intelectual secularist using more sophisticated view points. Hence relying on Salaafi to defend ahle sunnah wal Jammah is miss placed as they by their very literalist tendancy is averse to philosopy, logic and metaphysics. Should they decide to otherwise they are delving into school of thought and perhaps carry out their theft of thoughts from Muqalid scholars and spiritual master.
In addition, I also want when one is confronted with this new breed of relgious secularism, the next generation of intelectually driven muslim will have only following recourse 1. Get dissillusioned and become Aithistic due to lack of appropriate rebuttle 2. Ignore it and be in a state dissconnected from the happening by adopting an insular approach to life 3. Opt for tradtion with sound reasoning and tool available as to intiate a rebuttle.
From the list above one can assume most educated atleast the intelecually driven will opt for either 1 or 3.
In conclusion modern day Salaafism or Secular Salaafism gives rise to Secularism, Aithism and as a reaction revive Mutazilte trend.
May Allah protect us from the fitan of these ism in all shapes and form. Surely it is Allah who guides.
