Narated By AbuHurayrah : The Apostle of Allah (pbuh) said: When Allah created Paradise, He said to Gabriel: Go and look at it. He went and looked at it, then came and said: O my Lord! By Thy might, no one who hears of it will fail to enter it.
He then surrounded it with disagreeable things, and said: Go and look at it, Gabriel. He went and looked at it, then came and said: O my Lord! By Thy might, I am afraid that no one will enter it.
When Allah created Hell, He said: Go and look at it, Gabriel. He went and looked at it, then came and said: O my Lord! By Thy might, no one who hears of it will enter it.
He then surrounded it with desirable things and said: Go and look at it, Gabriel. He went, looked at it, then came and said: O my Lord! By Thy might and power, I am afraid that no one will remain who does not enter it.
