Is the method of ghusl (ritual bath) after janabah (state of ritual impurity) correct, taking into consideration the steps followed and the questions related to: frequent recitation of "Bismillah," invalidating the ghusl by washing inside the buttocks or the private parts during the ghusl, the effect of an incomplete or incorrect ghusl on fasting, and the ruling on the presence of a barrier (such as a hair or dirt) after the ghusl, and the permissible amount of barrier?

The tasmiyah (saying "Bismillah") belongs at the beginning of ghusl (ritual bath). Repeating it or touching the private parts does not invalidate the ghusl. Covering the entire body with water is sufficient to remove ritual impurity, but it is not the complete, recommended ghusl. Ghusl has two forms: complete and sufficient. If a barrier is found after ghusl, and it is likely to have appeared afterwards, it should be attributed to the nearest probable time. An error in ghusl does not affect the validity of fasting. It is more cautious to remove every barrier, and for a person suffering from waswasa (obsessive doubts), it is permissible to adopt the view of overlooking minor impurities.
