Walaikumassalam, yes I think that you did the correct thing because the first things that our mentioned like imkan al kidhb, imkan e nazir, and the kufriyya ibaraat of the 4 elders of Deoband are the issues that we have with Deobandis. In a video, I remember Shaykh Ul Islam Syed Madni Miya said that Sadrul Afazil Syed Naeemuddin Muradabadi Rahmatullahi Alayh said to only debate with Wahhabis on the matter of Kufriyyat of their elders not on furu'i issues. Warch the following video from 1:14:00
Asalamu `alaykum I had an encounter online with a pseudo-Ahle Hadith/Wahhabi who asked me the differences between us (Sunni Hanafis) and the Deobandi movement. I said imkan al kidhb, imkan e nazir, and the kufriyya ibaraat of the 4 elders of Deoband. If I said Mawlid, Qiyam, Fatiha, Urs, etc. or hadhir wa nadhir they'd say "these are all furui` issues" although hadhir wa nadhir is not furu`i Did I do right?
