The word(s) "laugh" appears 50 time(s) in 35 verse(s) in Quran in Mohsin Khan translation.

(1) And (remember) when Musa (Moses) said to his people: "Verily, Allah commands you that you slaughter a cow." They said, "Do you make fun of us?" He said, "I take Allah's Refuge from being among Al-Jahilun (the ignorant or the foolish)."

(2) He [Musa (Moses)] said, "He says, 'It is a cow neither trained to till the soil nor water the fields, sound, having no other colour except bright yellow.' " They said, "Now you have brought the truth." So they slaughtered it though they were near to not doing it.

(3) He has forbidden you only the Maitah (dead animals), and blood, and the flesh of swine, and that which is slaughtered as a sacrifice for others than Allah (or has been slaughtered for idols, on which Allah's Name has not been mentioned while slaughtering). But if one is forced by necessity without wilful disobedience nor transgressing due limits, then there is no sin on him. Truly, Allah is Oft-Forgiving, Most Merciful.

(4) And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad صلى الله عليه وسلم), the Hajj and 'Umrah (i.e. the pilgrimage to Makkah) for Allah. But if you are prevented (from completing them), sacrifice a Hady (animal, i.e. a sheep, a cow, or a camel) such as you can afford, and do not shave your heads until the Hady reaches the place of sacrifice. And whosoever of you is ill or has an ailment in his scalp (necessitating shaving), he must pay a Fidyah (ransom) of either observing Saum (fasts) (three days) or giving Sadaqah (charity - feeding six poor persons) or offering sacrifice (one sheep). Then if you are in safety and whosoever performs the 'Umrah in the months of Hajj before (performing) the Hajj, (i.e. Hajj-at-Tamattu' and Al-Qiran), he must slaughter a Hady such as he can afford, but if he cannot afford it, he should observe Saum (fasts) three days during the Hajj and seven days after his return (to his home), making ten days in all. This is for him whose family is not present at Al-Masjid-Al-Haram (i.e. non-resident of Makkah). And fear Allah much and know that Allah is Severe in punishment.

(5) And (remember) when Ibrahim (Abraham) said, "My Lord! Show me how You give life to the dead." He (Allah) said: "Do you not believe?" He [Ibrahim (Abraham)] said: "Yes (I believe), but to be stronger in Faith." He said: "Take four birds, then cause them to incline towards you (then slaughter them, cut them into pieces), and then put a portion of them on every hill, and call them, they will come to you in haste. And know that Allah is All-Mighty, All-Wise."

(6) Forbidden to you (for food) are: Al-Maitah (the dead animals - cattle - beast not slaughtered), blood, the flesh of swine, and that on which Allah's Name has not been mentioned while slaughtering, (that which has been slaughtered as a sacrifice for others than Allah, or has been slaughtered for idols) and that which has been killed by strangling, or by a violent blow, or by a headlong fall, or by the goring of horns - and that which has been (partly) eaten by a wild animal - unless you are able to slaughter it (before its death) - and that which is sacrificed (slaughtered) on An-Nusub (stone-altars). (Forbidden) also is to use arrows seeking luck or decision; (all) that is Fisqun (disobedience of Allah and sin). This day, those who disbelieved have given up all hope of your religion; so fear them not, but fear Me. This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion. But as for him who is forced by severe hunger, with no inclination to sin (such can eat these above mentioned meats), then surely, Allah is Oft-Forgiving, Most Merciful.

(7) They ask you (O Muhammad صلى الله عليه وسلم) what is lawful for them (as food). Say: "Lawful unto you are At-Tayyibat [all kind of Halal (lawful-good) foods which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. And those beasts and birds of prey which you have trained as hounds, training and teaching them (to catch) in the manner as directed to you by Allah; so eat of what they catch for you, but pronounce the Name of Allah over it, and fear Allah. Verily, Allah is Swift in reckoning."

(8) Made lawful to you this day are At-Tayyibat [all kinds of Halal (lawful) foods, which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. The food (slaughtered cattle, eatable animals) of the people of the Scripture (Jews and Christians) is lawful to you and yours is lawful to them. (Lawful to you in marriage) are chaste women from the believers and chaste women from those who were given the Scripture (Jews and Christians) before your time when you have given their due Mahr (bridal-money given by the husband to his wife at the time of marriage), desiring chastity (i.e. taking them in legal wedlock) not committing illegal sexual intercourse, nor taking them as girl-friends. And whosoever disbelieves in Faith [i.e. in the Oneness of Allah and in all the other Articles of Faith i.e. His (Allah's) Angels, His Holy Books, His Messengers, the Day of Resurrection and Al-Qadar (Divine Preordainments)], then fruitless is his work; and in the Hereafter he will be among the losers.

(9) So eat of that (meat) on which Allah's Name has been pronounced (while slaughtering the animal), if you are believers in His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(10) And why should you not eat of that (meat) on which Allah's Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors.
