Answer
Jazakumullahu khayran
Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.
Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In his response to your question, Sheikh Kifah Mustapha, the Imam and Director of The Prayer Center of Orland Park and representative for Dar El Fatwa of Lebanon in the US, states:
Wearing jewelry in Islam is permitted for females made of gold or other stones. Allah the Almighty said: “then is one reared amid ornaments.” (Az-Zukhruf 43:18)
But wearing jewelry should match cultural practices to be on the normal track and avoid imitating people of bad example.
So what I am trying to say is that, if one had jewelry on toes and it was a practice in her community or culturally inherited, it should be fine. But if practices are imitating other gender or people of bad example, it is not.
On the note of your second question, a woman can cut her hair for regrowth, yes because there is no text that prohibits that and the ruling in Islam is that: everything is permissible except that which God declared not.
Almighty Allah knows best.
