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
"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".
