Does a muslim man have to cut his hair a specific way?
Shaykh Muhammad ibn Ibraaheem rahimahu Allah said:
With regard to hair, the Prophet’s guidance is either to leave it all alone or to remove all of it. He did not shave part of it and leave part of it.
What some Muslims do, which is to shave part of the head and leave part, is the qaza’ (tuft) which was forbidden by the Prophet (peace and blessings of Allaah be upon him). This may take several forms:
1- Shaving some parts of the head and leaving others
2- Shaving the sides of the head and leaving the middle
3- Shaving the middle and leaving the sides
4- Shaving the front and leaving the back
5- Shaving the back and leaving the front
6- Shaving one side and leaving the other
The fact that these types are haraam is indicated by the report in al-Saheehayn from Ibn ‘Umar (may Allaah be pleased with him) who said, “The Messenger of Allaah (peace and blessings of Allaah be upon him) forbade qaza’, i.e., shaving parts of a boy’s hair and leaving other parts.” And it was narrated from him (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) saw a boy who had some of his hair shaved and some left; he forbade them from doing that and said: “Shave it all or leave it all.” And it was narrated from ‘Umar (may Allaah be pleased with him) in a marfoo’ report (i.e., attributed to the Prophet (peace and blessings of Allaah be upon him)): “Shaving the back of the head, unless it is for the purpose of cupping, is the act of the Magians.” In Sunan Abi Dawood it is narrated that Anas ibn Maalik (may Allah be pleased with him) saw a boy with his head shaved, leaving two braids or long locks, and he said, “Shave these or cut them, for this is the style of the Jews.” Al-Marwadhi said, “I asked Abu ‘Abd-Allaah (i.e., Ahmad ibn Hanbal) about shaving the back of the head, and he said, “That is what the Magians do, and whoever imitates a people is one of them.”

Proper Islamic Hijab ====>> It says in Fataawa al-Lajnah al-Daa’imah (5/175):
What is the ruling on leaving some of the hair longer than the rest?
Answer: Abu Dawood narrated from ‘Abd-Allaah ibn ‘Umar (may Allaah be pleased with him) that the Messenger of Allaah (blessings and peace of Allaah be upon him) forbade qaza’ and said: “Shave all of it or leave all of it.”
it says in Sharh al-Iqnaa’: Qaza’ includes shaving some places on the sides of the head, or shaving the middle and leaving the sides, as most of the Christians do, or shaving the sides and leaving the middle, as many of the foolish do, or shaving the front and leaving the back. Ahmad was asked about shaving the back of the head and he said: This is the action of the Magians, and whoever imitates a people is one of them. Thus it is known that it is not permissible to leave some parts of the hair longer than others.

Shaykh Ibn Jibreen (may Allaah preserve him) was asked: It has become common among women and men to cut their hair in such a way that there is an area that is 10 or 13 cm long, then they shave the hair on the sides and back of the head completely, leaving only the hair on the top of the head.
What is the ruling on that and what is the evidence? Does this come under the heading of qaza’ or not? Why?
He replied: There is no doubt that this action is wrong and is blind following of others, and it comes under the heading of qaza’. It was narrated that the Prophet (blessings and peace of Allaah be upon him) forbade qaza’; he saw a boy who had part of his head shaved and he said: “Shave all of it or leave all of it.” Moreover, this style is not beautification for either men or women, rather it is changing the creation of Allaah and spoiling people’s appearance, and it is an imitation of the West in which there is no benefit, in addition to the cost involved, as it involves a lot of effort and spending money on something that is harmful, as is well known. We advise men not to adopt this western style and we advise women to stick with that which their mothers and grandmothers did, of letting their hair grow and braiding it, as this is more beautiful. And Allaah is the one whose help we seek; may Allaah send blessings and peace upon Muhammad and his family and Companions. End quote from Fataawa al-Shaykh Ibn Jibreen.
