2:264 يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تُبْطِلُوا۟ صَدَقَٰتِكُم بِٱلْمَنِّ وَٱلْأَذَىٰ كَٱلَّذِى يُنفِقُ مَالَهُۥ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ فَمَثَلُهُۥ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ فَأَصَابَهُۥ وَابِلٌ فَتَرَكَهُۥ صَلْدًا لَّا يَقْدِرُونَ عَلَىٰ شَىْءٍ مِّمَّا كَسَبُوا۟ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَٰفِرِينَ
O you who believe! do not make your charity worthless by reproach and injury, like him who spends his property to be seen of men and does not believe in Allah and the last day; so his parable is as the parable of a smooth rock with earth upon it, then a heavy rain falls upon it, so it leaves it bare; they shall not be able to gain anything of what they have earned; and Allah does not guide the unbelieving people.
6:122 أَوَمَن كَانَ مَيْتًا فَأَحْيَيْنَٰهُ وَجَعَلْنَا لَهُۥ نُورًا يَمْشِى بِهِۦ فِى ٱلنَّاسِ كَمَن مَّثَلُهُۥ فِى ٱلظُّلُمَٰتِ لَيْسَ بِخَارِجٍ مِّنْهَا كَذَٰلِكَ زُيِّنَ لِلْكَٰفِرِينَ مَا كَانُوا۟ يَعْمَلُونَ
Is he who was dead then We raised him to life and made for him a light by which he walks among the people, like him whose likeness is that of one in utter darkness whence he cannot come forth? Thus what they did was made fair seeming to the unbelievers.
7:176 وَلَوْ شِئْنَا لَرَفَعْنَٰهُ بِهَا وَلَٰكِنَّهُۥٓ أَخْلَدَ إِلَى ٱلْأَرْضِ وَٱتَّبَعَ هَوَىٰهُ فَمَثَلُهُۥ كَمَثَلِ ٱلْكَلْبِ إِن تَحْمِلْ عَلَيْهِ يَلْهَثْ أَوْ تَتْرُكْهُ يَلْهَث ذَّٰلِكَ مَثَلُ ٱلْقَوْمِ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا فَٱقْصُصِ ٱلْقَصَصَ لَعَلَّهُمْ يَتَفَكَّرُونَ
And if We had pleased, We would certainly have exalted him thereby; but he clung to the earth and followed his low desire, so his parable is as the parable of the dog; if you attack him he lolls out his tongue; and if you leave him alone he lolls out his tongue; this is the parable of the people who reject Our communications; therefore relate the narrative that they may reflect.
