Question :
What is the ruling on istinja' after urination, and is it done with water and soap or with water only?
The Answer :
Istinja' from urine and stool is obligatory. It is permissible to perform istinja' with water alone, or with toilet paper alone. The best way is with toilet paper then water. If one wishes to suffice with one of them, then water is better. And Allah the Almighty knows best.
