The Difference Between Mani, Madhi, and Wadi

Question:
Honorable Shaykh, may Allah grant you success. He says: How does one distinguish between mani, madhi, and wadi? Is there a difference between them?

Answer:
Yes, there is a difference between them. If there were no difference, they would be one and the same. There is a difference between them. Refer to the books of hadith and fiqh and see. If Allah wills, mani is released with desire, and it is white in color and thick, accompanied by desire.
As for madhi, it is released with thinness when looking or when caressing the wife, with thinness. This is ritually impure, but it is a light impurity; sprinkling water is sufficient for it. As for mani, it is pure; it does not require a full ritual bath except for the sake of cleanliness only.
As for wadi, its ruling is the ruling of urine. Wadi is what comes out after finishing urination. This is its ruling: the ruling of urine. It is a heavy impurity that requires washing, just as urine is washed.
