Umm Salama told that the Prophet saw in her house a girl with saf’a, i.e. yellowness,* in her face and said:“Use an invocation for her, for she has been affected by the evil eye.”(Bukhari and Muslim.) * Saf’a is explained as a stroke from the devil, or the influence of the evil eye. It may be read suf’a which means blackness, or blackness tinged with red. Sufra 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.
