Summary
 Istinjā is a necessary and integral part of keeping clean. We must learn how to do it and do it properly. Both religiously and hygienically it is beneficial. It safeguards a person from catching infections, diseases, protects them from bad smells and most importantly keeps a person in a pure state from an Islamic point of view. All of the worship a person does will be valid. On the other hand, a person who stays impure does not fulfil the conditions of prayer. If any of the conditions of a prayer are not complete then the prayer will not be deemed valid. All of the effort and time will be futile. 
 Note: 
Ensure the whole body has been washed There are certain places in the body where people sometimes forget to wash or it may be difficult for water to reach these areas. Water must reach any opening in the body which is not sealed like an ear piercing. We must also ensure to wash the inner part of the navel and ensure that water reaches the all external parts of our private area. Water must also reach the skin under the eyebrows. If a female has long braids then as long as water reaches the roots of her hair, she will be exempt from undoing them.
