The ruling on a woman in the waiting period wearing black clothing during the 'iddah

Question:
The questioner says: Shaykh, in our country there is a custom of wearing black and adhering to it until the end of the 'iddah. What is the ruling of the Shari'ah on this?

Answer:
Adhering to black is not permissible. Wearing black in the 'iddah of death and the practice of ihdad is an innovation (bid'ah). The woman wears whatever colors are available to her, but she avoids clothing that is adornment; she avoids clothing that contains adornment. Yes.
