If the son of Adam were to possess two valleys of riches. he would long for the third one. And the stomach of the son of Adam is not filled but with dust. And Allah returns to him who repents.  

قَالَ رَسُولُ اللَّهِ ﷺ لَوْ كَانَ لاِبْنِ آدَمَ وَادِيَانِ مِنْ مَالٍ لاَبْتَغَى وَادِيًا ثَالِثًا وَلاَ يَمْلأُ جَوْفَ ابْنِ آدَمَ إِلاَّ التُّرَابُ وَيَتُوبُ اللَّهُ عَلَى مَنْ تَابَ  

I heard the Messenger of Allah ﷺ as saying this, but I do not know whether this thing was revealed to him or not, but he said to.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ فَلاَ أَدْرِي أَشَىْءٌ أُنْزِلَ أَمْ شَىْءٌ كَانَ يَقُولُهُ بِمِثْلِ حَدِيثِ أَبِي عَوَانَةَ  

If there were two valleys of gold for the son of Adam, he would long for another one. and his mouth will not be filled but with dust, and Allah returns to him who repents.  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ لَوْ كَانَ لاِبْنِ آدَمَ وَادٍ مِنْ ذَهَبٍ أَحَبَّ أَنَّ لَهُ وَادِيًا آخَرَ وَلَنْ يَمْلأَ فَاهُ إِلاَّ التُّرَابُ وَاللَّهُ يَتُوبُ عَلَى مَنْ تَابَ  

If there were for the son of Adam a valley full of riches, he would long to possess another one like it. and Ibn Adam does not feel satiated but with dust. And Allah returns to him who returns (to Him). Ibn Abbas said: I do not know whether it is from the Qur'an or not; and in the narration transmitted by Zuhair it was said: I do not know whether it is from the Qur'an, and he made no mention of Ibn Abbas.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَوْ أَنَّ لاِبْنِ آدَمَ مِلْءَ وَادٍ مَالاً لأَحَبَّ أَنْ يَكُونَ إِلَيْهِ مِثْلُهُ وَلاَ يَمْلأُ نَفْسَ ابْنِ آدَمَ إِلاَّ التُّرَابُ وَاللَّهُ يَتُوبُ عَلَى مَنْ تَابَ قَالَ ابْنُ عَبَّاسٍ فَلاَ أَدْرِي أَمِنَ الْقُرْآنِ هُوَ أَمْ لاَ وَفِي رِوَايَةِ زُهَيْرٍ قَالَ فَلاَ أَدْرِي أَمِنَ الْقُرْآنِ لَمْ يَذْكُرِ ابْنَ عَبَّاسٍ  

You are the best among the inhabitants of Basra, for you are the reciters among them. So continue to recite it. (But bear in mind) that your reciting for a long time may not harden your hearts as were hardened the hearts of those before you. We used to recite a surah which resembled in length and severity to (Surah) Bara'at. I have, however, forgotten it with the exception of this which I remember out of it:" If there were two valleys full of riches, for the son of Adam, he would long for a third valley, and nothing would fill the stomach of the son of Adam but dust." And we used so recite a surah which resembled one of the surahs of Musabbihat, and I have forgotten it, but remember (this much) out of it:" Oh people who believe, why do you say that which you do not practise" (lxi 2.) and" that is recorded in your necks as a witness (against you) and you would be asked about it on the Day of Resurrection" (xvii. 13).  

بَعَثَ أَبُو مُوسَى الأَشْعَرِيُّ إِلَى قُرَّاءِ أَهْلِ الْبَصْرَةِ فَدَخَلَ عَلَيْهِ ثَلاَثُمِائَةِ رَجُلٍ قَدْ قَرَءُوا الْقُرْآنَ فَقَالَ أَنْتُمْ خِيَارُ أَهْلِ الْبَصْرَةِ وَقُرَّاؤُهُمْ فَاتْلُوهُ وَلاَ يَطُولَنَّ عَلَيْكُمُ الأَمَدُ فَتَقْسُوَ قُلُوبُكُمْ كَمَا قَسَتْ قُلُوبُ مَنْ كَانَ قَبْلَكُمْ وَإِنَّا كُنَّا نَقْرَأُ سُورَةً كُنَّا نُشَبِّهُهَا فِي الطُّولِ وَالشِّدَّةِ بِبَرَاءَةَ فَأُنْسِيتُهَا غَيْرَ أَنِّي قَدْ حَفِظْتُ مِنْهَا لَوْ كَانَ لاِبْنِ آدَمَ وَادِيَانِ مِنْ مَالٍ لاَبْتَغَى وَادِيًا ثَالِثًا وَلاَ يَمْلأُ جَوْفَ ابْنِ آدَمَ إِلاَّ التُّرَابُ وَكُنَّا نَقْرَأُ سُورَةً كُنَّا نُشَبِّهُهَا بِإِحْدَى الْمُسَبِّحَاتِ فَأُنْسِيتُهَا غَيْرَ أَنِّي حَفِظْتُ مِنْهَا { يَا أَيُّهَا الَّذِينَ آمَنُوا لِمَ تَقُولُونَ مَا لاَ تَفْعَلُونَ} فَتُكْتَبُ شَهَادَةً فِي أَعْنَاقِكُمْ فَتُسْأَلُونَ عَنْهَا يَوْمَ الْقِيَامَةِ
