What is the method for performing a complete ritual bath (ghusl) after major ritual impurity (janabah)? Is it sufficient to pour water over the hair and body for this? Is it obligatory to perform istinja' (washing of private parts) after bathing? What is required if istinja' was not performed before prayer? Is it necessary to say "A'udhu billahi min al-khubuthi wal-khaba'ith" (I seek refuge with Allah from the male and female evil spirits) when entering the bathroom, and what is the wisdom behind that?

Ghusl (ritual bath) after janabah (state of ritual impurity due to sexual activity) is of two types: one that is sufficient, achieved by forming the intention and ensuring water covers the entire body, including rinsing the mouth and nose; and a complete ghusl, which is superior. Upon passing urine or feces, it is obligatory to perform istinja' with water or istijmar with stones, with istinja' being preferable. As for the supplication upon entering the lavatory, "Allahumma inni a‘udhu bika min al-khubuthi wal-khaba’ith" (O Allah, I seek refuge in You from male and female evil spirits), it is recommended and not obligatory.
