With regard to
parting the hair on the side, this involves imitating the Kafir (disbelieving) women, and it is proven that the Messenger of Allah (peace be upon him) said it is Haram (prohibited) to imitate the Kafirs. With regard to gathering the hair and letting it hang down on the back, either braided or not, there is nothing wrong with that so long as it is covered. However, making it into a bun (on top of the head) is not permitted, because that is an imitation of Kafir women and it is Haram to imitate them. The Prophet (peace be upon him) warned against that when he said:
"There are two types amongst the denizens of the Fire whom I have not seen yet: Men having whips like the tails of cows with which they flog people, and women who would be naked in spite of their being dressed, who seduce others (to wrong paths) and are being seduced; their heads will appear like the humps of the Bactrian camels inclined to one side. These (women) would not enter Jannah (Paradise) nor perceive its odor, even though its odor can be perceived at such and such (very remote) distance."
Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family, and Companions!
