وَعَن ابْن عَبَّاس قَالَ: من تعلم كتاب الله ثمَّ ابتع مَا فِيهِ هَدَاهُ اللَّهُ مِنَ الضَّلَالَةِ فِي الدُّنْيَا وَوَقَاهُ يَوْمَ الْقِيَامَةِ سُوءَ الْحِسَابِ وَفِي رِوَايَةٍ قَالَ: مَنِ اقْتَدَى بِكِتَابِ اللَّهِ لَا يَضِلُّ فِي الدُّنْيَا وَلَا يَشْقَى فِي الْآخِرَةِ ثُمَّ تَلَا هَذِهِ الْآيَةَ: (فَمَنِ اتَّبَعَ هُدَايَ فَلَا يضل وَلَا يشقى) رَوَاهُ رزين

Ibn ‘Abbas said that if anyone learns God’s Book and follows its contents, he will be guided by God away from error in this world and be guarded by Him on the day of resurrection from the strictest account. A version renders him as saying that one who models his life on God’s Book will not go astray in this world, or be miserable in the next. Then he recited this verse, “He who follows my guidance will not go astray or be miserable.” 1 Razin transmitted it. 1 Quran xx, `123.
