حَدَّثَنِي سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ دَاوُدَ، عَنْ أَبِي حَرْبِ بْنِ أَبِي، الأَسْوَدِ عَنْ أَبِيهِ، قَالَ 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 .
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).
