Bismillâh, wal-hamdulillâh
With regard to removing or not removing hair, the scholars divide hair into three categories:
1. That which sharî’ah commands us to leave alone and forbids us to remove any of it.
2. That which sharî’ah commands us to remove.
3. That concerning which sharî’ah says nothing; it does not tell us to remove it or forbid us to do so.
1- The hair which we are forbidden to remove includes the eyebrows & the beard. A woman must leave whatever makes her beautiful, so she is forbidden to shave the hair on her head.
The evidence for that is the hadîth of ‘Abdullâh ibn Mas’ûd (radiyallâhu `anhu) who said: I heard the Messenger of Allâh (صلى الله عليه وسلم) say: “Allâh has cursed the woman who does tattoos and the one who has them done, the woman who plucks eyebrows (an-nâmisah) and the one who has it done (an-mutanammisah), and the one who files her teeth for the purpose of beauty, altering the creation of Allâh.”
(Narrated by al-Bukhâri & Muslim)
And it was narrated that ‘Abdullâh ibn ‘Umar (radiyallâhu `anhumâ) said: I heard the Messenger of Allâh (صلى الله عليه وسلم) say: “Be different from the mushrikîn (polytheists): let your beards grow and trim your moustaches.” (Narrated by al-Bukhâri & Muslim)
2 – The hair which we are commanded to remove or shorten are known as Sunan al-Fitrah, such as removing the pubic hairs, trimming the moustache and plucking the armpit hairs. That also includes shaving or cutting the all of the hair of the head during Hajj or ‘Umrah.
The evidence for that is the hadîth of ‘Â’ishah (radiyallâhu `anhâ) who said: The Messenger of Allâh (صلى الله عليه وسلم) said: “Ten (actions) are part of the fitrah [natural inclinations of man]: trimming the moustache, letting the beard grow, using the siwâk (toothbrush from the roots of the Arak/Peelu tree), rinsing the nose with water, clipping the nails, washing the finger joints, plucking the armpit hairs, shaving the pubic hair and washing oneself with water after relieving oneself.”
Zakariyyâ said: Mus’ab said: And I forgot the tenth but it may have been rinsing the mouth with water (Narrated by Muslim)
3 – Hair concerning which the Qur'ân & Sunnah are silent about and do not say whether it is to be removed or left as it is, such as hair on the head (except during `Umrah & Hajj), legs, hands, cheeks, nose, chest, back & arms.
There is some difference of scholarly opinion concerning this.
Some said that it is not permissible to remove it, because removing it implies changing the creation of Allâh, as Allâh tells us that the Shaytân said:
“'...and indeed I will order them to change the nature created by Allâh'” [TMQ an-Nisâ’ 4:119]
Some said that this is one of the things concerning which nothing was said, so the ruling is that it is allowed. It is permissible to leave it or to remove it, because whatever is not mentioned in the Qur’aan or Sunnah is permissible.
The Prophet (صلى الله عليه وسلم) said: “What is halâl is that which Allâh has permitted in His Book, and what is harâm is that which Allâh has forbidden in His Book, and what He has remained silent about is forgivable.” (Narrated by al-Tirmidhi)
Shaving, trimming or leaving alone the hair on the head, legs, hands, cheeks, nose, chest, back & arms is forgivable according to the above hadîth, so there is no problem with shaving, trimming or leaving alone the above hairs. In other words, it is your personal choice.
And Allah Knows Best
