What is wrong with this statement? Any hadith that geos against Quran should be discarded as rasullah saw could not have said anything contrary to Quran. The promise of preservation is about Quran not for hadith. What is your complaint? Are you dull?
PS: This is the problem with copy/paste. You don’t understand what you are copy/pasting but are too mad for loosing the death of isa argument that stupidly digging another hole for yourself.
