While quoting any Hadith as a Reference and a source to reach at some conclusion, we must need to see the status of such Hadith, I mean there are a lot of Hadiths which are either Dhaeef(weak),Fabricated or Un-Traceable(except Sahih Bukhari & Sahih Muslim).
Also we must need to be very careful in quoting the text of Hadiths, as all the companions of Prophet(MPUH)were used to do extra-ordinary care when quoting any Hadith.
Hazrat Abdullah Bin Masood(RA) who was one of the most closest of Prophet’s companions, used to add following words after quoting any Hadith;
" May be something less or something more "
God knows better.
