Praise be to Allaah.
Both husband and wife should make themselves attractive to one another, in ways that the other likes, so as to strengthen their relationship, but this has to be within the limits of what is allowed in sharee’ah, not by doing things that are prohibited. The use of wigs started among non-Muslim women, who were so well known for wearing them and adorning themselves with them that this became one of their distinguishing features. If a woman wears a wig and adorns herself with it, even if she does this for her husband, she is imitating the kaafir women, which the Prophet (peace and blessings of Allaah be upon him) forbade: “Whoever imitates a people is one of them.” Wigs also come under the ruling about hair extensions, which is even more vehement in its prohibition: the Prophet (peace and blessings of Allaah be upon him) forbade this practice and cursed the one who does it.Fataawa al-Lajnah al-Daa’imah, 5/191.
Humayd ibn ‘Abd al-Rahmaan ibn ‘Awf reported that he heard Mu’aawiyah ibn Abi Sufyaan at the time of Hajj, standing on the minbar and holding a piece of hair that had been seized by his guards, saying: “Where are your scholars? I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) forbidding this kind of thing and saying that Bani Israa’eel were destroyed when their women started to use such things.” Abu Hurayrah (may Allaah be pleased with him) reported that the Prophet (peace and blessings of Allaah be upon him) said: “Allaah has cursed the woman who adds false hair and the woman who has this done, and the woman who tattoos and the women who has this done.”(Reported by al-Bukhaari, 5477). And Allaah knows best.
