وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ قَالَ كُنْتُ أَنَا وَمُحَمَّدُ بْنُ يَحْيَى بْنِ حَبَّانَ، جَالِسَيْنِ فَدَعَا مُحَمَّدٌ رَجُلاً فَقَالَ أَخْبِرْنِي بِالَّذِي، سَمِعْتَ مِنْ، أَبِيكَ ‏.‏ فَقَالَ الرَّجُلُ أَخْبَرَنِي أَبِي أَنَّهُ، أَتَى زَيْدَ بْنَ ثَابِتٍ فَقَالَ لَهُ كَيْفَ تَرَى فِي قِرَاءَةِ الْقُرْآنِ فِي سَبْعٍ فَقَالَ زَيْدٌ حَسَنٌ وَلأَنْ أَقْرَأَهُ فِي نِصْفٍ أَوْ عَشْرٍ أَحَبُّ إِلَىَّ وَسَلْنِي لِمَ ذَاكَ قَالَ فَإِنِّي أَسْأَلُكَ ‏.‏ قَالَ زَيْدٌ لِكَىْ أَتَدَبَّرَهُ وَأَقِفَ عَلَيْهِ ‏.‏

Yahya related to me from Malik that Yahya ibn Said said, "OnceMuhammad ibn Yahya ibn Habban and I were sitting down, and Muhammadcalled a man over to him and said to him, 'Tell me what you have heardfrom your father.' The man replied that his father had told him thathe went to Zayd ibn Thabit and asked him, 'What do you think ofreciting the whole Qur'an in seven days?' Zayd said, 'That's good,but I prefer to recite it in two weeks, or ten days. Ask me why thatis.' He said, 'I ask you then.' Zayd said, 'So that I can reflect onit and pause in it.'
