Question:
May Allah reward you with good. What is the method of ghusl? And are detergents such as shampoo used? May Allah reward you with good.

Answer:
The obligatory or recommended ghusl is characterized by the way the Prophet (peace and blessings be upon him) did it. The complete method, as the Prophet (peace and blessings be upon him) did it, is to first perform istinja', then perform wudu' for prayer, delaying the washing of the feet. Then he pours water over his head three times, saturating it and reaching the roots of his hair. Then he pours water over his body three times, starting with the right side. This is the complete method, accompanied by the intention from the beginning of the purification. He also says the name of Allah at the beginning, saying "Bismillah." Then he washes his feet when he has finished the ghusl. If he washed them with the wudu' before the ghusl, there is no harm. He has a choice between the two. The sufficient amount for ghusl is to pour water over his entire body once, so that nothing remains of it without water reaching it. This is the sufficient amount. Yes.
