What were the promises made by Allah (SWT) to the pious worshipers that no eye has seen, no ear has heard, and nobody has thought of according to Prophet Muhammad (saw)?
 Narrated Abu Huraira:                     Allah's Apostle said, "Allah said, 'I have prepared for my pious worshipers such things as no eye has ever seen, no ear has ever heard of, and nobody has ever thought of." Abu Huraira added: If you wish you can read:-- 'No soul knows what is kept hidden (in reserve) for them of joy as reward for what they used to do.' 32.17.
