What is the Sharia ruling with regards to wearing colored contact lenses for females?
In the name of Allah, the Most Gracious, the Most Merciful.
Assalamualaikum Warahmatullahi Wabarakatuhu
It is permissible for a female to wear colored contact lenses for beautifying herself only for her husband. If there is any form of deception by wearing colored contact lenses, it will not be permissible.
Nabi Salallāhu Alayhi Wasallam mentions,
مَنْ غَشَّنَا فَلَيْسَ مِنَّا
“Whoever deceives us, he is not from amongst us.”
