Mehndi... is a form of body art from Ancient India, in which decorative designs are created on a person's body... -- Mehndi, Wikipedia
Some online fatawa say it's recommended:
- Mufti Yaseen Shaikh (MuftiSays): "It is recommended for women to apply Henna" giving the reason "In view of the above quoted hadith one of the reasons for females applying mehndi is to distinguish her hands from that of a male."
Some online fatawa say it's permissible:
Qibla.com (sourced from IslamQA.org): "Yes, a woman can wear hennah, and her wudu will be valid."
Mufti Ebrahim Desai, Askimam.org: "It is permissible for women to use black henna on their hands and feet."
Zikr: "The Shariah (Islamic law) allows women to use henna."
While others say it is haram or makruh:
Qibla.com (sourced from IslamQA.org): "It seems that a non-married woman wearing henna is not a sunna and it is either makruh or haram. Or so says Anwar Al-Masalik."
Abu Yahya, Qibla.com (sourced from IslamQA.org): "Yes, it is offensive (makrooh) for an unmarried woman to wear henna on her hands or feet."
Question: Who says women dying their hands with henna is (im)permissible?
Since there's inconsistent scholarly opinion, I'm seeking an overview of the different scholarly thoughts regarding the permissibility of henna depending on sect/school of thought. (...if possible, if not an answer explaining why this is impossible [or prohibitively difficult] would be fine).
