Ruling for something is based on shariah. The hair on the body is something that is not talked about in it. If sharia doesnt say anything about it then is allowable for a woman to remove them. The hair on arms and legs does not come under the same heading as the hair that is commanded or recomended to remove i.e. pubic hair. And it does not come under the heading that are comanded or forbidden to remove i.e. hair of eyebrows and on head.
Because shariah says nothing about it the s holars differ on opinion concerning it. While some say it is not permissible as it changes the creation of Allah.
Allaah tells us that the Shaytaan said:
“ ‘and indeed I will order them to change the nature created by Allaah’”
[al-Nisa’ 4:119 – interpretation of the meaning]
Others say it is permissible to remove them because it is one of the things concerning which sharee’ah did not say anything, so the ruling is that it is permissible, since whatever sharee’ah did not say anything about in the Qur’aan or Sunnah is allowable, as it says in the hadeeth: “What is halaal is that which Allaah has permitted in His Book, and what is haraam is that which Allaah has forbidden in His Book, and whatever He has not said anything about is allowable.” Narrated by al-Tirmidhi, 1726; classed as hasan by al-Albaani in Saheeh al-Tirmidhi.
The view that it is permitted is the view favoured by the Standing Committee, and also by Shaykh Ibn ‘Uthaymeen. See Fataawa al-Mar’ah al-Muslimah, 3/879; Majmoo’ Fataawa Ibn ‘Uthaymeen, 11/q. 64.
Sometimes a woman does not want to do that but her husband asks her to do so. It must ve noted that it is mustahabb for husband and wife to beautify themselves for each other because Allah says in glorious Quran:
“and live with them honourably”
“And they (women) have rights similar (to those of their husbands) over them to what is reasonable”
Hence if a husband tells his wife to make herself good for him and remove the hairs on body then she has to do it, because that is his right and because obeying the husband in that which is good and proper is obligatory for her. Al-Mawsoo’ah al-Fiqhiyyah, maadat al-tazayyun, 11/271.
She is obliged to obey her husband and do so if that will not cause her any harm and does not involve her in something haraam.
However, the husband should forego his right to ask his wife to do that if she convinces him that this causes her hardship or she does not want to do it and so on.
Another aspect is that most of the women go to saloon for this service, it must be noted that there is nothing wrong with that as long as these conditions are met.
1. Hair must be removed by a woman and there is no male present there. The place must be trustworthy as nowadays often such places have cameras installed and people are corrupt. Sisters should be carefull before taking any step.
2. The woman who does the waxing should not see any part of the awrah of another woman i.e. awrah should not be uncovered. The awrah includes the torao and thighs and if one visits a saloon then let waxing be limited to only arms and lower legs.
3. The salon should not be a place where ‘awrahs are uncovered. The scholars have stated that it is haraam for a woman to enter public baths because they are places where ‘awrahs are uncovered. Al-Albaani (may Allaah have mercy on him) said: The public baths are definitely haraam for women. It was narrated that Abu Maleeh said: Some women from Syria entered upon ‘Aa’ishah (may Allaah be pleased with her) and she said: “Who are you?” They said: “From the people of Syria.” She said: “Perhaps you are from al-Koorah where women enter the public baths?” They said: “Yes.” She said: “I heard the Prophet (peace and blessings of Allaah be upon him) say: ‘There is no woman who takes off her clothes anywhere but in her own house, but she has torn (the veil of modesty) between her and Allaah.’” Narrated by the authors of the four Sunans, and its isnaad is saheeh according to the conditions of al-Saheehayn. Tamaam al-Minnah 130).
Hence a full body hair removal and sauna baths and massages must be avoided to protect oneself from haraam. If you can do it yourself, good, if not, leave it.
And Allaah knows best.
