ALHAMDULILLAH, You can argue there’s far more important things to worry about but purity is in all aspects of your life. The main underlying factor is that adopting any hairstyle that entails shaving some part of the head and leaving the other unshaved is impermissible or at the least disliked and explicitly prohibited by the Messenger of Allah (صلى الله عليه وسلم ).
1. Nafi’ reports that he heard Abdullah ibn Umar say: “I heard the Messenger of Allah (صلى الله عليه وسلم ) forbidding the practice of Qaz’a.” Ubaidullah said: “I inquired, what is Qaz’a?” So he said: “When the head of a child is shaved and hair is left here and there, and Ubaidullah pointed towards his forelock and the sides of his head.”
– Sahih al-Bukhari, No. 5576
2. Abdullah ibn Umar narrates that: “The Messenger of Allah (صلى الله عليه وسلم ) saw a child, part of whose head was shaved and the other unshaven. The Messenger of Allah (صلى الله عليه وسلم ) forbade them (the Companions) from doing this and said: “ Either shave it completely or leave it completely.”
– Sunan Abu Dawud, No. 4192
Moreover, this style is not beautification for either men or women, rather it is changing the creation of Allah 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.
Take note of this too;
1.Men should not look like women
2. Women should not look like men
3. Muslims should not imitate kafir
4. Imitating the Prophet صلى الله عليه وسلم Is the best.
The Prophet صلى الله عليه وسلم Said anybody that imitate kufar are part of them.
Shaykh Ibn ‘Uthaymeen said:
With regard to the phrase “imitation of the kuffaar”, that does not mean that we should not use anything that they have manufactured. No one says such a thing. At the time of the Prophet (peace and blessings of Allaah be upon him) and afterwards the people used to wear clothes made by the kuffaar and use vessels made by them.
Imitation of the kuffaar means imitating their clothing and appearance, and the customs that are unique to them. It does not mean that we should not ride what they ride or wear what they wear. But if they ride in a specific way that is unique to them, then we should not ride in that way. If they tailor their clothes in a certain fashion that is unique to them, if the cut their hair in a certain fashion that is unique to them, we should not do likewise. But if we have cars that are similar to theirs and fabric that is similar to theirs, there is nothing wrong with that.
Majmoo’ Fataawa al-Shaykh Ibn ‘Uthaymeen , 12, question 177.
With wisdom and humbleness, let us take part of our time to spread the dawah, to admonish our dear brothers and sisters, our beloved friends that are blindfolded that this act of doing Qa’za [ shaving part of the head and leaving other] is totally dislike/forbidding in this religion of ours.
Some will heed to your advice while others will turn back, at least you have done your part. But it’s better for them to know now before their quota of reminder finish.
