There is a ruling for Sayyed Sistani, where he states that if the water smells the odor of a excrements for example, it’s najis.

What if, if one keeps one cleaning but even after around 1 hour of cleaning (applying shampoos), there is still odor, and this isn’t a one time only thing, going to the bathroom results in a minimum of 1 hour just to put out excrements. Am I missing something? Does the ruling differ in my situation? Whenever I smell my hand after putting out excrements my hand smells excrements. Even when I wash with soap, whenever I wipe my hand after finishing to see if the odor is still there, the odor is still present in the water that’s on the anus
