AhsanAllahu ilaykum. Ruling (purity) on treated sewage water used for agriculture (clear, *sometimes* has a faint smell)? Some came on me before salah once (dried) Is sitting with parents and paternal uncle considered free-mixing? Ruling on reconstructing a fish skull (real bones) for display?

Treated sewage water, if it is purified completely such that the characteristics of impurity (taste, colour, and smell) are removed, becomes pure and purifying once again, and it is permissible to use it for purification, washing clothes, and irrigating crops. Freemixing is women and men sitting together chitchating laughing etc. I do not know about the fish part.
