1. Delaying a ghusl until the time of a prayer is about to leave.
2. For a female not to pray an obligatory prayer after her menstrual cycle stops.
For example, her cylcle stopped before the period of zhur was over and the time ramaining for that prayer was enough to pray one raka’a of prayer. In this case it is obligatory on her to take a bath and pray zhur. The Prophet ﷺ said: “He who performs a raka’a of Subh prayer before the sun rises, has met (the time for) Salatul Subh. And he who performs a raka’a of Asr prayer before sunset, has met (the time for) Salatul ‘Asr.” [ agreed upon],
1- If a womans hair is braided, she’s not obliged to undo her braids to perform a ghusl. This applies to purification from a menstrual cycle or janabah.
2- It is recommended for the woman to take a piece of cotton/tissue, put musk on it and wipe the path the blood used to take after she has bathed due to her menstrual cycle stopping.
3- If a muslim makes a ghusl to purify himself from major hadath and prays, his prayer is valid, whether he intended wudu’ with it or not.
