وَأَمَّا قَدْرُ السَّبَقِ فِي الِابْتِدَاءِ: كَانَ أَبُو حَنِيفَةَ رَحِمَهُ اللهُ يَحْكِي عَنِ الشَّيْخِ الْقَاضِي الْإِمَامِ عُمَرَ بْنِ أَبِي بَكْرٍ الزَّرَنْجَرِيِّ رَحِمَهُ اللهُ أَنَّهُ قَالَ: قَالَ مَشَايِخُنَا رَحِمَهُمُ اللهُ: يَنْبَغِي أَنْ يَكُونَ قَدْرُ السَّبَقِ لِلْمُبْتَدِئِ قَدْرَ مَا يُمْكِنُ ضَبْطُهُ بِالْإِعَادَةِ مَرَّتَيْنِ بِالرِّفْقِ وَيَزِيدُ كُلَّ يَوْمٍ كَلِمَةً حَتَّى أَنَّهُ وَإِنْ طَالَ وَكَثُرَ يُمْكِنُ ضَبْطُهُ بِالْإِعَادَةِ مَرَّتَيْنِ، وَيَزِيدُ بِالرِّفْقِ وَالتَّدْرِيجِ، وَأَمَّا إذَا طَالَ السَّبَقُ فِي الِابْتِدَاءِ وَاحْتَاجَ إلَى الْإِعَادَةِ عَشْرَ مَرَّاتٍ فَهُوَ فِي الِانْتِهَاءِ أَيْضًا يَكُونُ كَذَلِكَ، لِأَنَّهُ يَعْتَادُ ذَلِكَ، وَلَا يَتْرُكُ تِلْكَ الْإِعَادَةَ إلَّا بِجُهْدٍ كَثِيرٍ وَقَدْ قِيلَ: السَّبَقُ حَرْفٌ، وَالتَّكْرَارُ أَلْفٌ.
As for how much lesson to take when beginning: Abū Ḥanīfa, may Allah have mercy on him, related from Shaykh the judge, Imām ʿUmar ibn Abī Bakr al-Zaranjī, may Allah have mercy on him, that he said: Our shaykhs, may Allah have mercy on them, said: A beginner's lesson should be only as much as he can master with two gentle repetitions, increasing by a word each day — so that even when it grows long, two repetitions still suffice, adding gently by gentle steps. But if the opening lesson is so long that it needs ten repetitions, at the end of study it will be the same, for he will have grown used to that and will not drop those repetitions without great effort. And it is said: The lesson is one letter; repetition, a thousand.
