Umm Salama told that the Prophet (ﷺ) saw in her house a girl with <i>saf’a</i>, i.e. yellowness,* in her face and said:

“Use a spell for her, for she has been affected by the evil eye.” (Bukhari and Muslim.) * <i>Saf’a</i> is explained as a stroke from the devil, or the influence of the evil eye. It may be read <i>suf’a</i> which means blackness, or blackness tinged with red. <i>Sufra</i> normally means yellowness, but it can also mean blackness, and that may be the interpretation it should have here, in which case one should read suf'a.

وَعَنْ أُمِّ سَلَمَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى فِي بَيْتِهَا جَارِيَةً فِي وجهِها سفعة يَعْنِي صُفْرَةً فَقَالَ: «اسْتَرْقُوا لَهَا فَإِنَّ بِهَا النَّظْرَةَ»
