Dispute between Hell and Paradise
The Prophet (sal Allahu alaihi wa sallam) said, “There was a dispute between Hell and Paradise, and Hell said: ‘The haughty and proud are in me.’ Paradise said: ‘In me are the weak and the humble.’ Thereupon Allah, the Exalted, judged between them saying: ‘You the Paradise are My Mercy, and through you I shall show mercy to those whom I wish.’ (And addressing the Hell) He said: ‘You are My punishment to punish whom I wish amongst My slaves, and each one of you will have its fill.”’
This Hadith warns us against haughtiness and pride and urges us to observe modesty and humility.
Paradise and Hell have been called as the manifestations of Allah’s Mercy and punishment. True, only the Will of Allah prevails everywhere but the decision to send a man either to Paradise or to Hell will not be taken capriciously. Rather set Divine rules will be working behind it. Allah, will place some people in Paradise due to their good deeds; similarly he will place some people in Hell due to their bad deeds. Allah does not wrong anyone.
And Allah knows best!
