Why the jewel prayer put the blood on the people?

The Jewel Prayer, or "Dua al-Nudba," is a significant supplication in Islamic tradition, particularly among Shia Muslims. The reference to blood in this context often symbolizes the deep emotional and spiritual connection to the suffering of the Imams and the injustices faced by the oppressed. The act of putting blood on people can be seen as a manifestation of mourning and solidarity with those who have suffered, reflecting themes of sacrifice, loss, and the quest for justice in the face of tyranny.
