Hadhrat Maulana Ashraf Ali Thaanwi 
states:
"Ibn Taymiyyah and Ibn Qayyim were master and student. They were very intelligent, and masters of the pen. Their pace exceded that of a motor car. Then (at full speed) they didn’t look who came in front of them in the street-be it a child or an animal. They just went forward at full speed, continuing their own discourse without regard to what others said. This is not the way of a people who make true Tahqeeq. (Magar yeh tarz Shaan Tahqiq nahin) Their manner of discourse would be harsh . Ibn Taymiyyah(ra) did a lot of service for the deen . He was born with a harsh temperament and such was his fitra. But the kaamil(perfected individual) is he who has the perfect balance between ilm and adab , and keeps both in due perspective."
