The Torah states (Leviticus 19:14): "You shall not curse the deaf nor place a stumbling block before the blind; you shall fear your God - I am your Lord."
19:14 Waa inaadan caayin qofkii dhega la', oo kii indha la'na waa inaadan hortiisa dhigin wax lagu turunturoodo, laakiinse waa inaad Ilaahaaga ka cabsataa, waayo, aniga ayaa Rabbiga ah.
