Yahya ibn ‘Abbad reported: Ali ibn Abi Talib, may Allah be pleased with him, said, “Verily, the jurist is truly one of understanding, who never lets people despair of the mercy of Allah, who never grants them a concession to disobey Allah, who never lets them feel secure from the punishment of Allah, and who never abandons the Quran seeking anything else. Verily, there is no good in worship without knowledge, nor in knowledge without understanding, nor in recitation without reflection.”

عَنْ يَحْيَى ابْنُ عَبَّادٍ عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ إِنَّ الْفَقِيهَ حَقَّ الْفَقِيهِ مَنْ لَمْ يُقَنِّطِ النَّاسَ مِنْ رَحْمَةِ اللَّهِ وَلَمْ يُرَخِّصْ لَهُمْ فِي مَعَاصِي اللَّهِ وَلَمْ يُؤَمِّنْهُمْ مِنْ عَذَابِ اللَّهِ وَلَمْ يَدَعِ الْقُرْآنَ رَغْبَةً عنْهُ إِلَى غَيْرِهِ إِنَّهُ لَا خَيْرَ فِي عِبَادَةٍ لَا عِلْمَ فِيهَا وَلَا عِلْمٍ لَا فَهْمَ فِيهِ وَلَا قِرَاءَةٍ لَا تَدَبُّرَ فِيهَا
