حَدَّثَنَا مَحْمُودُ بْنُ غَيْلَانَ حَدَّثَنَا أَبُو دَاوُدَ أَنْبَأَنَا شُعْبَةُ عَنْ مَنْصُورٍ قَال سَمِعْتُ أَبَا وَائِلٍ عَنْ عَبْدِ اللَّهِعَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ بِئْسَمَا لِأَحَدِهِمْ أَوْ لِأَحَدِكُمْ أَنْ يَقُولَ نَسِيتُ آيَةَ كَيْتَ وَكَيْتَ بَلْ هُوَ نُسِّيَ فَاسْتَذْكِرُوا الْقُرْآنَ فَوَالَّذِي نَفْسِي بِيَدِهِ لَهُوَ أَشَدُّ تَفَصِّيًا مِنْ صُدُورِ الرِّجَالِ مِنْ النَّعَمِ مِنْ عُقُلِهِقَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ

Narrated to us [Mahmud bin Ghailan] has related to us [Abu Dawud] has related to us [Syu'bah] from [Mansur] he said : I heard [Abu Wa`il] from [Abdullah] from the Prophet peace be upon him , he said: "How bad it is for one of them or one of you to say; "I forgot such and such a verse," even he is forgetful (created with a forgetful nature), therefore memorize the Qur'an, by the One in Whose hand is my soul, the release (of the Qur'an) from a person's heart is more terrible than the release of a camel from its tether." Abu Isa said : This hadith is hasan sahih.
