This crime is so great that it will be pointed out in Hell and then punishment will be meted out, as it is said in a Hadith. Hazrat Abdullah Ibn Umar says that the denizens of Hell will first call the superintendent of Hell, they will keep calling him but they will not receive any reply. At last they will receive the reply after 40 years. The superintendent of Hell will say, ‘Abide herein only.’ Then they will directly complain to Allah and say: - 

The answer to this complaint will be given to them after a very, very long time - time equal to the interregnum between the creation and the end of the world. And when the answer will be given, it will be this: -

Now these people will be completely disheartened and will continue to bray like donkeys while being singed. Then their faces will undergo change and they will be distorted. Then some occupants of Paradise will come to them with the permission for intercession but will not be able to recognise any one. The denizens of Hell will say that they were such and such but the occupants of Paradise will say: "This is wrong; we don't recognise you" 

Now the denizens of Hell will call Allah and will receive the afore-said answer. Then the doors of Hell will be closed and they will continue to rot there. To put them to shame and to make them repentant of a prodigious sin, a heinous crime of theirs will be pointed out to them that they used to make fun of the beloved bondmen of Allah and used to make their invocations the topic for jesting, which Allah Most High describes in the Quran thus: - 

It is known from this verse also that scoffing and sneering is a special sign and a peculiar crime of the infidels and the denizens of Hell- a crime that takes man to Hell. Besides this verse, it has been stated in several verses of the Quran. As such, Allah Most High says in Surah-e Al-Mutaffif’in as under: - 

Regarding this Ibn Kathir states that these infidels had gained the upper hand; they used to poke fun at the believers and used to jeer at them while coming and going, and used to despise and humiliate them, and on meeting their own people used to talk nonsense and concoct stories about the believers. They used to get what they wished but thanking for divine bounties apart, bent on the contrary for infidelity, they used to go harassing the Muslims, and because the Muslims did not agree with them, they used to call Muslims astray. 

Allah Most High says that these infidels had not been sent as guardians over the Muslims. Why were they then anxious about the Muslims, always pursuing them? What business had they to look after their actions and why did they indulge in gibing and taunting them? 

On the Day of Judgement the believers would be laughing at the disbelievers and, sitting on couches, would be enjoying the greatest pleasure of gazing at their Allah, which is a clear proof of the fact that they were not astray although the disbelievers used to call them astray. The disbelievers would receive the full compensation for what they sued to do with the believers in the world. They would be laughed at for the fun that they used to make of the Muslims. They used to depreciate the Muslims but Allah appreciated them. 

It is known from these verses that jeering and gibing is a peculiar sign of those who disbelieve in Allah and His prophets and are the enemies and foes of His saints. Hence it will be no wonder if people having this habit will be resurrected along with Allah's and His Apostle's enemies, even as it has been said that those who renounce prayers will rise up along with Pharoah, Haman, etc. because there is a common factor of disobedience with them in giving up praying; just as Pharoah and Haman and others of their like used to make fun of the prophets, they also make fun of Allah's chosen slaves.
