1. Washing the parts of the body in order and consecutively when doing Ghusl is not obligatory according to the majority of jurists. 2. The more correct scholarly view is that rinsing the mouth and nose is obligatory in both Wudu and Ghusl. 3. If a man or woman does Ghusl to remove major impurity, this Ghusl counts for Wudu too. 4. Wudu and Ghusl are valid even if any bits of food remain between the teeth, but removing them is better.

Ghusl is invalid if performed while menses has not yet ceased completely. Purity is confirmed either by the appearance of a white discharge or complete dryness (no discharge). If Ghusl is performed before confirming purity, then the Ghusl must be repeated for prayers to be valid. However, if a woman becomes certain of her purity before Fajr (even without repeating ghusl), her fast for that day remains valid.

If someone thinks that he had a wet dream, then he wakes up and does not find any wetness, he does not have to do Ghusl.

If Ghusl does not meet these conditions, it is broken: 1- intention to remove impurity, 2- purity of water, 3- the water should reach the entire body, 4- continuity between the parts of Ghusl and not allowing any lengthy interruption between them.
