The textbook also lists good omen (التفاؤل), ill omen (التطير), and firm recording or declaration (التسجيل) among possible purposes for stating a proper name. These are rhetorical descriptions of associations and attitudes, not a treatment of the religious permissibility of particular superstitions.
تفاؤل — invoking a name with favorable associations.
تطيّر — invoking a name because of, or to suggest, an unfavorable omen.
تسجيل — placing an assertion on record with a sense of firmness or formality.
Different hearers may react differently to the same name. The intended function must therefore be inferred from meaning, convention, and occasion, not from the letters alone.
