Paradise is the tremendous reward which Allah (swt) has prepared for His beloved (awliyaa) and those who obey Him. It is complete joy and pleasure, where nothing is lacking and nothing can disturb its purity. What Allah (swt) and His Messenger have told us about it makes out heads spin because our minds are not able to comprehend the greatness of such blessings.

Listen to the words of Allah (swt) in this hadith qudsi:
I have prepared for My righteous slaves that which no eye has seen, no ear has heard and has never crossed the mind of any human being“.

Then the Prophet (saw) said, “Recite, if you wish: “No person knows what is kept hidden for them of joy as a reward for what they used to do”. (32:17)

The joys of Paradise are far greater than the pleasures of this world, which pale into insignificance in comparison. al-Bukhaari reports from Sahl ibn Sa’d as-Sa’idee that the Messenger of Allah (saw) said: “A space the size of a whip in Paradise is better than this world and al that is in it“. (Fath al-Baari, 6/319, an-Nawawi’s commentary on Muslim 17/166)

Because admittance to Paradise and salvation from the Fire are according to Allah’s will and judgement, it is a great victory and tremendous success, as Allah (swt) says:
Only he who is saved far from the Fire and admitted to the Garden, will have indeed attained the object of life [or: been successful]” (3:185)

Allah has promised to believers – men and women – Gardens under which rivers flow, to dwell therein [forever], and beautiful mansions in Gardens of everlasting bliss. But the greatest bliss is the Good Pleasure of Allah. That is the supreme felicity [or success]“. (9:72)

“…and those who obey Allah and His Messenger will be admitted to Gardens with rivers flowing underneath, to abide therein [forever] and that will be the supreme achievement“. (4:13)
