What is the ruling on a woman wearing black clothing as mourning for her husband and continuing to wear it beyond the prescribed period of mourning out of grief for her husband because she loves him?

The questioner : She says that she is a woman whose husband passed away seven years ago, and since his death, she has been wearing black clothing, whether inside the house or outside. She says, "I did not wear these clothes before, but because of the intensity of my grief for him, I wore black, and I continued wearing it after the known mourning period ended, up to this moment when I am writing to you. My intention is that this is to avoid displaying adornment, because in my belief, the color black does not draw attention. Therefore, I would like you to clarify the Islamic ruling on this, may Allah reward you."

The Shaykh : We see that this woman is an innovator, and it is not permissible for her to mourn for more than what the Shari'ah has prescribed: four months and ten days if she is not pregnant, and until she gives birth if she is pregnant.
Even for the woman in mourning, it is not a condition of the mourning period that she restrict herself to black; rather, she may wear whatever she wishes, except that she does not wear clothes of adornment. So my advice to this questioner is to fear Allah (Mighty and Majestic), and to return to normal life in her clothing, as well as in perfume and other things, because the Shari'ah has limited the mourning period to four months and ten days for one who is not pregnant, and to the delivery of the child for one who is pregnant.
And these clothes that she has kept will renew her sorrows; whenever she wants to forget the calamity, these clothes renew it. So let her fear Allah regarding herself, and let her follow what the Shari'ah has brought, and let her wear whatever clothes she wishes now.
