حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا إِسْحَاقُ بْنُ يُوسُفَ، عَنِ الْعَوَّامِ بْنِ حَوْشَبٍ، عَنْ أَبِي مُحَمَّدٍ، مَوْلَى عُمَرَ بْنِ الْخَطَّابِ عَنْ أَبِي عُبَيْدَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ مَنْ قَدَّمَ ثَلاَثَةً مِنَ الْوَلَدِ لَمْ يَبْلُغُوا الْحِنْثَ كَانُوا لَهُ حِصْنًا حَصِينًا مِنَ النَّارِ ‏"‏ ‏.‏ فَقَالَ أَبُو ذَرٍّ: قَدَّمْتُ اثْنَيْنِ ‏.‏ قَالَ: ‏"‏ وَاثْنَيْنِ ‏"‏ ‏.‏ فَقَالَ أُبَىُّ بْنُ كَعْبٍ أَبُو الْمُنْذِرِ سَيِّدُ الْقُرَّاءِ: قَدَّمْتُ وَاحِدًا ‏.‏ قَالَ" ‏"‏ وَوَاحِدًا ‏"‏ ‏.‏
