There are some metaphors in some verses of the Qur'an. These metaphors, that the All-Wise Allah makes, are very effective and advance the understanding of those who read them. Every one of these metaphors and descriptions illustrates the subject in the most effective and the clearest way.

As for those who deny Our Signs and are arrogant regarding them, the Gates of Heaven will not be opened for them, and they will not enter the Garden until a camel goes through a needle's eye. That is how We repay the evildoers (Surat al-A'raf, 40)

We will advance on the actions they have done and make them scattered specks of dust. (Surat al-Furqan, 23)

The metaphor of those who reject their Lord is that their actions are like ashes scattered by strong winds on a stormy day. They have no power at all over anything they have earned. That is extreme misguidance. (Surah Ibrahim, 18)

The parable of those who reject Faith is as if one were to shout like a goat-herd, to things that listen to nothing but calls and cries: Deaf, dumb, and blind, they are void of wisdom. (Surat al-Baqara, 171)

The metaphor of those who take protectors besides Allah is that of a spider which builds itself a house; but no house is flimsier than a spider's house, if they only knew. (Surat al-Ankabut, 41)

You who believe! Do not nullify your charity by demands for gratitude or insulting words, like him who spends his wealth, showing off to people and not believing in Allah and the Last Day. His likeness is that of a smooth rock coated with soil, which, when heavy rain falls on it, is left stripped bare. They have no power over anything they have earned. Allah does not guide disbelieving people. (Surat al-Baqara, 264)

The metaphor of what they spend in their life in this world is that of a wind with an icy bite to it which strikes the crops of a people who have wronged themselves and destroys them. Allah did not wrong them; rather it was themselves they were wronging. (Surah Al 'Imran, 117)

The call of truth is made to Him alone. Those they call upon apart from Him do not respond to them at all. It is like someone stretching out his cupped hands towards water to convey it to his mouth: it will never get there. The call of the disbelievers only goes astray. (Surat ar-Ra'd, 14)

The metaphor of those who spend their wealth, desiring the pleasure of Allah and firmness for themselves, is that of a garden on a hillside. When heavy rain falls on it, it doubles its produce; and if heavy rain does not fall, there is dew. Allah sees what you do. (Surat al-Baqara, 265)

Be people of pure natural belief in Allah, not associating anything else with Him. As for anyone who associates others with Allah, it is as though he had fallen from the sky and the birds had seized him and carried him away or the wind had dropped him in a distant place. (Surat al-Hajj, 31)

If We had wanted to, We would have raised him up by them. But he gravitated towards the earth and pursued his whims and base desires. His metaphor is that of a dog: if you chase it away, it lolls out its tongue and pants, and if you leave it alone, it lolls out its tongue and pants. That is the metaphor of those who deny Our Signs. So tell the story so that hopefully they will reflect. (Surat al-A'raf, 176)

Hold fast to the rope of Allah all together, and do not separate. Remember Allah's blessing to you when you were enemies and He joined your hearts together so that you became brothers by His blessing. You were on the very brink of a pit of the Fire and He rescued you from it. In this way Allah makes His Signs clear to you, so that hopefully you will be guided. (Surah Al 'Imran, 103)

Who is better: someone who founds his building on fear of Allah and His good pleasure, or someone who founds his building on the brink of a crumbling precipice so that it collapses with him into the Fire of Hell? Allah does not love wrongdoers. (Surat at-Tawba, 109)

Those who believe say, 'If only a sura could be sent down.'But when a straightforward sura is sent down and fighting is mentioned in it, you see those with sickness in their hearts looking at you with the look of someone about to faint from fear of death. More fitting for them would be obedience and honourable words. Once the matter is resolved upon, being true to Allah would be better for them. (Surah Muhammad, 20-21)

When they came at you from above you and below you, when your eyes rolled and your hearts rose to your throats, and you thought unworthy thoughts about Allah, at that point the believers were tested and severely shaken. (Surat al-Ahzab, 10-11)

Do not consider Allah to be unaware of what the wrongdoers perpetrate. He is merely deferring them to a Day on which their sight will be transfixed, rushing headlong - heads back, eyes vacant, hearts hollow. (Surah Ibrahim, 42-43)

The Trumpet will be blown and at once they will be sliding from their graves towards their Lord. (Surah Ya Sin, 51)

He Who created the seven heavens in layers. You will not find any flaw in the creation of the All-Merciful. Look again - do you see any gaps? Then look again and again. Your sight will return to you dazzled and exhausted! (Surat al-Mulk, 3-4)
