Mujahid said that the meaning of «مهين» is weak, feeble (or insignificant), referring to a man's semen. The meaning of «ضللنا» is "we are destroyed." Ibn Abbas (may Allah be pleased with them both) said «جرز» is the land where there is very little rain, from which no benefit is derived (or hard and dry land). The meaning of «يهد» is "we explain."
Narrated Abu Huraira: Allah's Messenger 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.
