* Majority Opinion (Hanafi, Shafi'i, and Maliki schools):
* If water can reach the scalp easily without undoing the braids or ties, then it is not obligatory to undo them. The important thing is to ensure that water reaches the roots of the hair and the scalp.
* If the hair is tightly braided or tied in a way that water cannot easily reach the scalp, then it is obligatory to undo it so that water can properly cleanse the scalp.
* Some Scholars (including some within the Hanbali school):
* They may suggest it's preferred or obligatory to loosen the hair, especially if it's long and densely braided, to ensure complete purification.
Important Points:
* Practicality: The key consideration is whether water can reach the scalp effectively. If the hair is loose enough or the braids are not too tight, simply pouring water over the head and massaging the scalp is sufficient.
* Burden: Islam aims to ease burdens. If undoing the hair is extremely difficult or would cause hardship (e.g., if it takes a very long time to redo intricate braids), then it's generally understood that it's not obligatory if water can still reach the scalp.
* Proof from Hadith: There is a hadith where Umm Salamah asked the Prophet Muhammad (peace be upon him) whether she had to undo her hair for ghusl. He replied that it was sufficient to pour water over her head three times, provided that the water reached the roots of her hair.
In summary, the prevailing view is that it's not always necessary to undo the hair during ghusl. The essential thing is to ensure that water thoroughly cleanses the scalp.
It is advisable to consult with a knowledgeable Islamic scholar for personalized guidance, as interpretations can vary based on specific circumstances.
