Truly thou canst not cause the Dead to listen, nor canst thou cause the Deaf to hear the call, (especially) when they turn back in retreat.
Nor canst thou be a guide to the Blind, (to prevent them) from straying: only those will thou get to listen who believe in Our Signs, and they will bow in Islam.[Qur'an 27:80-81]
Narrated Abu Hurayrah(RA): The Prophet (peace_be_upon_him) said: There will be civil strife (fitnah) which will render people deaf, dumb and blind regarding what is right. Those who contemplate it will be drawn by it, and giving rein to the tongue during it will be like smiting with the sword.
