If she is wearing jewelry when her husband dies, must she remove it, or should we say that continuing something already in place is less stringent than initiating it?

We say: she must take it off. The same applies to a tooth [of gold], if it can be removed. Usually, however, it cannot be removed, so she does not remove it, but should take care that it is not visible.

If the jewelry is made of something other than gold or silver—such as emeralds, pearls, or diamonds—it is subject to the same ruling as gold and silver; indeed, it may be even more alluring.

His statement, “black kohl”: kohl may be classed as beautification. Thus, she may not use black kohl, neither at night nor during the day.

Some scholars have said that she may use it at night when needed, and wipe it off during the day.

The correct view is that it is not permissible at all, because the Prophet ﷺ was asked for permission concerning this. They said to him, “May we apply kohl to her?” He replied, “No.” He was asked this three times, but he ﷺ refused. (1) This proves that it is absolutely impermissible.

Anything other than kohl, such as eye drops, medicine, and the like, does not constitute adornment. Hence the author says:

“No tūtiyā.” In our colloquial dialect, it is called tūt, without the final yāʾ.
