I want to know whether gusl haiz and gusl janabat are two different things.

After menses or after intercourse, Ghusl becomes compulsory. There are three Fardh in Ghusl, a) To gargle the mouth, b) To rinse the nose so that the water touches the soft part of the bone in both the nostrils, and c) To make sure that the water reaches every strand of hair on the body, at least once. However, with regards to the woman's hair on her head, then there is details.

If she has plaited hair and the water comfortably reaches the roots of her hair, then it is not necessary for her to undo her plaits. If her hair is thick and the water will not be able to reach the roots of her hair, then it is compulsory for her to undo her plaits so that the water can reach the roots. In any case, it is not necessary for the water to reach the inbetween hairs of the plaits.

As for the Sunnats of Ghusl, then one should first wash both the hands upto the wrists. Thereafter, wash all the impurities including the private parts, the hair behind the knees, under arms and neck. Thereafter, one should make a complete and perfect Wudhu and then throw water over the entire body three times.

and Allah Ta'ala Knows Best
