I heard in one dars regarding abbreviating the writing of the salawat etc. something very strong which was related from Imam Nawawi, inshaAllah I will try and look through my notes because it was something that made me ensure not to abbreviate again.
The Shar'i ruling of a particular action is determined by referring back to the correct sources. The practice of people posting on Sunniforum is not a Shar'i evidence.
Dear Brother, Assalaamoalikum,
What are the correct sources concerning the issue under discussion?
