1. 7:176Al-ArafCommand
   وَلَوۡ شِئۡنَا لَرَفَعۡنَٰهُ بِهَا وَلَٰكِنَّهُۥٓ أَخۡلَدَ إِلَى ٱلۡأَرۡضِ وَٱتَّبَعَ هَوَىٰهُۚ فَمَثَلُهُۥ كَمَثَلِ ٱلۡكَلۡبِ إِن تَحۡمِلۡ عَلَيۡهِ يَلۡهَثۡ أَوۡ تَتۡرُكۡهُ يَلۡهَثۚ ذَّـٰلِكَ مَثَلُ ٱلۡقَوۡمِ ٱلَّذِينَ كَذَّبُواْ بِـَٔايَٰتِنَاۚ فَٱقۡصُصِ ٱلۡقَصَصَ لَعَلَّهُمۡ يَتَفَكَّرُونَ
   And had We willed We could have raised him by their means, but he clung to the earth and followed his own lust. Therefor his likeness is as the likeness of a dog: if thou attackest him he panteth with his tongue out, and if thou leavest him he panteth with his tongue out. Such is the likeness of the people who deny Our revelations. Narrate unto them the history (of the men of old), that haply they may take thought.
   In context

   If Allah had desired, He would have made this person benefit through these signs, enabling him to act according to them, so that he would be raised up in this world and in the next. But he chose what led to his failure, being attracted to the desires of the worldly life, and preferring them to the Afterlife.

2. 18:18Al-Kahf
   وَتَحۡسَبُهُمۡ أَيۡقَاظٗا وَهُمۡ رُقُودٞۚ وَنُقَلِّبُهُمۡ ذَاتَ ٱلۡيَمِينِ وَذَاتَ ٱلشِّمَالِۖ وَكَلۡبُهُم بَٰسِطٞ ذِرَاعَيۡهِ بِٱلۡوَصِيدِۚ لَوِ ٱطَّلَعۡتَ عَلَيۡهِمۡ لَوَلَّيۡتَ مِنۡهُمۡ فِرَارٗا وَلَمُلِئۡتَ مِنۡهُمۡ رُعۡبٗا
   And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them.
   In context

   You - O one who looks at them - will think they are awake, because their eyes are open, though in actual fact they are asleep. I turn them over in their sleep, sometimes to the right and sometimes to the left, so that the earth does not consume their bodies. Their dog that accompanied them stretches out its forelegs at the entrance of the cave.

3. 18:22Al-Kahf
   سَيَقُولُونَ ثَلَٰثَةٞ رَّابِعُهُمۡ كَلۡبُهُمۡ وَيَقُولُونَ خَمۡسَةٞ سَادِسُهُمۡ كَلۡبُهُمۡ رَجۡمَۢا بِٱلۡغَيۡبِۖ وَيَقُولُونَ سَبۡعَةٞ وَثَامِنُهُمۡ كَلۡبُهُمۡۚ قُل رَّبِّيٓ أَعۡلَمُ بِعِدَّتِهِم مَّا يَعۡلَمُهُمۡ إِلَّا قَلِيلٞۗ فَلَا تُمَارِ فِيهِمۡ إِلَّا مِرَآءٗ ظَٰهِرٗا وَلَا تَسۡتَفۡتِ فِيهِم مِّنۡهُمۡ أَحَدٗا
   (Some) will say: They were three, their dog the fourth, and (some) say: Five, their dog the sixth, guessing at random; and (some) say: Seven, and their dog the eighth. Say (O Muhammad): My Lord is Best Aware of their number. None knoweth them save a few. So contend not concerning them except with an outward contending, and ask not any of them to pronounce concerning them.
   In context

   Some of those who delve into their incident will say about their number: They were three and their dog was the fourth amongst them. Others will say: They were five and their dog was the sixth amongst them. Both groups only said this as a guess without any proof. Some of them will say: They were seven and their dog was the eighth amongst them.
