Regarding Ghusl

Question Detail:

I have some issue realating to ghusl .. when i did ghusl .. i have always waswasah  regarding some place dry left .. i t take about 40 min to complete my ghusl .. 

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
When performing ghusl, pour water once on the entire body and then pass your hand on the entire body. In this way, you can be rest assured that the entire body is wet. This should take you about 5 to 7 minutes. Do not give in to waswasah as that is from shaytaan to create an imbalance in you. You should also seek professional help. Consult your physician who will diagnose you and offer you appropriate medicine to overcome your waswasah.
