He deserves paradise who makes his companions laugh.  Attributed to
the Qur'an, can you cite sura and verse?

I am convinced the quotation is not part of the Koran (or Qur'an).

I concluded this after going to this site,

Just Another Qur'an Browser
http://www.quranbrowser.com/

and searching on the terms "paradise," "companions" and "laugh."  No
verses even remotely similar were found. This search tool uses seven
English translations, making it extremely unlikely that that the
absence of the quote is due to differences in translation.

I also searched at these sites:

MSA-USC Qur'an Database 
http://www.usc.edu/dept/MSA/reference/searchquran.html

The Koran
http://www.hti.umich.edu/k/koran/simple.html

Those searches found the same verses, but not the one you sought.

It is possible that Mohammed made such a statement, but if he did it
isn't in the Qur'an.

Sincerely,

Mvguy-ga






Search strategy: I found several places where the Qur'an could be
searched by using the search terms "Koran" and "concordance" on
Google.
://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=utf-8&q=koran+concordance

A search at the following Koran search site failed to turn up any
similar verse:

I'm not giving this as an answer yet because of the possibility that
the translation uses different English words than than those in the
quote given.

Hi,
I am a Muslim and my first language is Arabic, that is why I conducted
my research in the original language of the Quran (Arabic).
Here is a list of mentions of any laugh, laughter, laughing, or any
derivative of the word laugh.
There are about 10 citations where laugh is mentioned, mainly in the
context of mocking, but still there are a few that signifies laughter
(or apparently at least), I included three example: the first 53:43
(Sourat Al Nagm), God Describing himself as "That it is He Who
granteth Laughter and Tears"
And in 80:39 (Sourat A'bas), describing the fiddles going into heaven:
 "Some Faces that Day will be beaming(38)Laughing, rejoicing (39)"
and one that is touching: the Prophet Soliman, after being able to
hear the ants telling each other to hide because he and his army can
crush them all, 27:19, (Sourat Al Naml) "So he smiled, amused at its
speech; and he said: "O my Lord! so order me that I may be grateful
for Thy favors, which Thou hast bestowed on me and on my parents, and
that I may work the righteousness that will please Thee: and admit me,
by Thy Grace, to the ranks of Thy righteous Servants.", and this verse
reveals one of the key words of Islam (and other religion), that is
"Thy Grace" (God's Mercy) , you may have noticed that it is like a
phrase stopper, in the original arabic it is clearer of course.
and here is a list of all the verses that includes laughter that i was
able to find:
9:82
11:71
23:110
27:19
43:47
53:43
53:60
80:39
83:29
83:34 

As for the exact verse you asked about, there is no laughter mentioned
at all. It bears a description of the infidels going on judgment day
going to Hell: "So they accused them of falsehood, and they became of
those who were destroyed."

I hope that it did help.
you can always use this link that is very easy to use, just choose the
Surat Number from the left menu, write the verse number in the right
combo box and this site will display the verse in Arabic with its
English Translation.
http://quran.al-islam.com/Targama/DispTargam.asp?nType=1&nSeg=0&l=eng&nSora=1&nAya=1&t=eng
( i think you should use cut and paste here)
It has also multiple translations to six languages.
You can also go to the site and navigate about Islam, Quran, Sunnah
