1) DRAWING BLOOD DURING FAST
The first contradictory hadith: Drawing blood violates a fast.
Tirmizi Fast, Abu Davud Fast, Bukhari Fast.
The second contradictory hadith: Drawing blood was administered to the Prophet while observing the fast.
Abu Davud Fast, Tirmizi Fast, Bukhari Medicine.
It goes without saying that had drawing blood violated his fast, the Prophet would not have let his blood be taken. It is explicitly stated in the Quran that eating, drinking and sexual intercourse are the three things that violate a fast. This shows that not only the two hadiths exclude each other but the first also contradicts the Quran. This quotation from three books considered the most reliable is evidence of the infiltration of false hadiths into books.
