أَخْبَرَنَا إِسْمَاعِيل بْنُ أَبَانَ ، حَدَّثَنَا مَسْعُودٌ ، عَنْ يُونُسَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي فَرْوَةَ ، عَنْ شُرَحْبِيلَ بْنِ أَبِي سَعْدٍ ، قَالَ : دَعَا الْحَسَنُ رَضِيَ اللهُ عَنْهُ بَنِيهِ وَبَنِي أَخِيهِ، فَقَالَ : " يَا بَنِيَّ وَبَنِي أَخِي،إِنَّكُمْ صِغَارُ قَوْمٍ يُوشِكُ أَنْ تَكُونُوا كِبَارَ آخَرِينَ، فَتَعَلَّمُوا الْعِلْمَ، فَمَنْ لَمْ يَسْتَطِعْ مِنْكُمْ أَنْ يَرْوِيَهُ، أَوْ قَالَ : يَحْفَظَهُ فَلْيَكْتُبْهُ، وَلْيَضَعْهُ فِي بَيْتِهِ "

Ismail bin Aban told us, Masoud told us, on the authority of Yunus bin Abdullah bin Abi Farwa, on the authority of Sharhabeel bin Abi Saad, he said: Al-Hasan, may God be pleased with him, called his sons and his brother’s sons and said: “O my sons and my brother’s sons, you are small people and you are about to become great others. So learn knowledge, and whoever among you is not able to narrate it, or say: he memorizes it, let him write it down and put it in his house.”
