Those that rule must hear and be deaf, must see and be blind.

Hear, ye deaf; and look, ye blind, that ye may see.

A good husband should be deaf and a good wife should be blind

What! can you then make the deaf to hear or guide the blind and him who is in clear error? / But if We should take you away, still We shall inflict retribution on them; / Rather We will certainly show you that which We have promised them; for surely We are the possessors of full power over them.

None so deaf as those that will not hear. None so blind as those that will not see.

Kindness is the language which the deaf can hear and the blind can see.
