Having a False Image of the Sunnah
If any open-minded individual were to study the Quran and the lives of the Infallibles (a), they would obtain an image of Islam that is quite different to what is being promoted by some Muslims.
In order to understand the reasons for the discouragement of blood rituals, we must always keep in mind the lifestyles of the Prophets (a) and Imams (a), and the general theme of the Quran, and to compare all of these to the observance of the blood shedding ceremonies. If we were to do this, we would come to the conclusion that these ceremonies are far removed from the Sunnah and the general teachings of Ahlulbayt (a). The Holy Prophet (s) and his family (a) have never taken part in any ceremony that resembles the blood rituals that we see today.
We must not allow our imaginations to conjure up unjustified notions that force blood shedding rituals into the Sunnah of the Ahlulbayt (a); instead we must accept the truth of the matter and admit the fact that these acts are very alien to the lifestyles of the Prophets (a) and the Ahlulbayt (a).
