Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
If it is highly probable that the wetness on damp ground is from altered sewage water, then the ground is ritually impure (najis). This ground becomes pure if rain falls upon it, covering the impurity, or if a flood washes it away, as stated by Imam Al-Shafi'i. However, if it is not known or highly probable that the ground has been altered by sewage water, then the default is that it remains pure, because certainty is not removed by doubt.
