The word(s) "laugh" appears 19 time(s) in 18 verse(s) in Quran in Muhammad Pickthal translation.

(1) And slay them wherever ye find them, and drive them out of the places whence they drove you out, for persecution is worse than slaughter. And fight not with them at the Inviolable Place of Worship until they first attack you there, but if they attack you (there) then slay them. Such is the reward of disbelievers.

(2) When ye have divorced women, and they have reached their term, then retain them in kindness or release them in kindness. Retain them not to their hurt so that ye transgress (the limits). He who doeth that hath wronged his soul. Make not the revelations of Allah a laughing-stock (by your behaviour), but remember Allah's grace upon you and that which He hath revealed unto you of the Scripture and of wisdom, whereby He doth exhort you. Observe your duty to Allah and know that Allah is Aware of all things.

(3) For that cause We decreed for the Children of Israel that whosoever killeth a human being for other than manslaughter or corruption in the earth, it shall be as if he had killed all mankind, and whoso saveth the life of one, it shall be as if he had saved the life of all mankind. Our messengers came unto them of old with clear proofs (of Allah's Sovereignty), but afterwards lo! many of them became prodigals in the earth.

(4) And (remember) when We did deliver you from Pharaoh's folk who were afflicting you with dreadful torment, slaughtering your sons and sparing your women. That was a tremendous trial from your Lord.

(5) It is not for any prophet to have captives until he hath made slaughter in the land. Ye desire the lure of this world and Allah desireth (for you) the Hereafter, and Allah is Mighty, Wise.

(6) Then let them laugh a little: they will weep much, as the reward of what they used to earn.

(7) And his wife, standing by laughed when We gave her good tidings (of the birth) of Isaac, and, after Isaac, of Jacob.

(8) But ye chose them for a laughing-stock until they caused you to forget remembrance of Me, while ye laughed at them.

(9) And (Solomon) smiled, laughing at her speech, and said: My Lord, arouse me to be thankful for Thy favour wherewith Thou hast favoured me and my parents, and to do good that shall be pleasing unto Thee, and include me in (the number of) Thy righteous slaves.

(10) Accursed, they will be seized wherever found and slain with a (fierce) slaughter.
