If you are ture Salafi than this not for you, if you are Ahle-Hadtih who originated from india, and mostly live in sub-continent than you better know this than me, or if you don't know then go and read the literature of hardcore Ahle-Hadtih, which mostly in Urdu. However the new generation Ahle-Hadtih of sub-continent are slowly transforming into Salafis. Their predecessors were go to the Saudia Arabia for Dirham and Dinar but when they go back to their homeland they had got some sense of Quran and Hadith. Anyways, to cut long story in short, Ahle-Hadith are slowly abandoning their illiteracy and transforming into Salafis which is good news.
