Assalam o alaykum, An ustadh of Abu Dawud at a madrasah in the subcontinent says that Hadhrat Saharanpuri, in explaining this hadith, has mentioned the Shafi'i position on isbal not the Hanafi one. And this is not a fatwa anyway. The position in line with the Hanafi usuls - as adopted by Deobandi scholars including Hadhrat - can be viewed here: http://deoband.org/2009/05/fiqh/misc...ride-in-isbal/
