"in the year of Tabuk, the Messenger of Allah ﷺ addressed the people, while leaning against his mount. He said: 'Shall I not tell you of the best of the people and the worst of the people? Among the best of the people is a man who strives in the cause of Allah on the back of his horse, or on the back of his camel, or on his own two feet, until death comes to him. And among the worst of the people, is an immoral man (Fajir) who reads the Book of Allah but he does not refrain from doing anything bad because of it.'" (Using translation from Nasāʾī 3106)
أَنَّهُ قَالَ إِنَّ رَسُولَ اللهِ ﷺ عَامَ تَبُوكَ خَطَبَ النَّاسَ وَهُوَ مُسْنِدٌ ظَهْرَهُ إِلَى نَخْلَةٍ فَقَالَ أَلَا أُخْبِرُكُمْ بِخَيْرِ النَّاسِ وَشَرِّ النَّاسِ إِنَّ مِنْ خَيْرِ النَّاسِ رَجُلًا عَمِلَ فِي سَبِيلِ اللهِ عَلَى ظَهْرِ فَرَسِهِ أَوْ عَلَى ظَهْرِ بَعِيرِهِ أَوْ عَلَى قَدَمَيْهِ حَتَّى يَأْتِيَهُ الْمَوْتُ وَإِنَّ مِنْ شَرِّ النَّاسِ رَجُلًا فَاجِرًا جَرِيئًا يَقْرَأُ كِتَابَ اللهِ وَلَا يَرْعَوِي إِلَى شَيْءٍ مِنْهُ
