Zainab bint Abu Salama reported that when the news of the death of Abu Safyan came to Umm Habiba she sent for yellow (perfume) on the third day and rubbed it on her forearms and on her cheeks and said: I had in fact no need of it, but I heard Allah's Messenger (ﷺ) as saying: It is not permissible for the women believing in Allah and the Hereafter to abstain from adornment beyond three days except (at the death of) husband (in which case she must abstain from adornment) for four months and ten days.
