Haḍra is like a big circle dance that Sufi Muslims do in North Africa and the Middle East. Everyone stands in a circle, holding hands or linking arms, and they all move together to music and chants. It's like a big party, but also a way for people to feel closer to God and to each other.
The people in the circle might wear special clothes, like long robes or colorful scarves, and they might have candles or incense burning. Sometimes they will also do special rhythmic clapping or say certain words or phrases to help them focus their minds and connect with their spiritual energy.
People who do haḍra often say that it helps them feel a deep sense of joy and happiness, and that it helps them let go of worries and stresses in their lives. It's a way to celebrate life, feel a sense of community, and find peace in the presence of others who share the same spiritual beliefs.
