سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، قَالَ نَظَرَ النَّبِيُّ صلى الله عليه وسلم إِلَى رَجُلٍ يُقَاتِلُ الْمُشْرِكِينَ، وَكَانَ مِنْ أَعْظَمِ الْمُسْلِمِينَ غَنَاءً عَنْهُمْ فَقَالَ: مَنْ أَحَبَّ أَنْ يَنْظُرَ إِلَى رَجُلٍ مِنْ أَهْلِ النَّارِ فَلْيَنْظُرْ إِلَى هَذَا. فَتَبِعَهُ رَجُلٌ فَلَمْ يَزَلْ عَلَى ذَلِكَ حَتَّى جُرِحَ، فَاسْتَعْجَلَ الْمَوْتَ. فَقَالَ بِذُبَابَةِ سَيْفِهِ، فَوَضَعَهُ بَيْنَ ثَدْيَيْهِ، فَتَحَامَلَ عَلَيْهِ، حَتَّى خَرَجَ مِنْ بَيْنِ كَتِفَيْهِ. فَقَالَ النَّبِيُّ صلى الله عليه وسلم: إِنَّ الْعَبْدَ لَيَعْمَلُ فِيمَا يَرَى النَّاسُ عَمَلَ أَهْلِ الْجَنَّةِ، وَإِنَّهُ لَمِنْ أَهْلِ النَّارِ، وَيَعْمَلُ فِيمَا يَرَى النَّاسُ عَمَلَ أَهْلِ النَّارِ وَهْوَ مِنْ أَهْلِ الْجَنَّةِ، وَإِنَّمَا الأَعْمَالُ بِخَوَاتِيمِهَا.
Hazrat Sahl bin Sa‘d as-Sa‘idira narrated that the Prophetsa observed a man who was fighting against the idolaters and was among the most effective of the Muslims in battle. The Prophetsa said, “Whoever wishes to see a man from among the dwellers of the Fire, let him observe this man.” So someone followed him closely until [the fighter] was wounded. Seeking to hasten death, he placed the tip of his sword between his chest and pressed upon it until it passed through his shoulders [thus taking his own life].
The Prophetsa then remarked, “A person may appear, in the eyes of the people, to be performing the deeds of the inhabitants of Paradise, yet he is actually among the inhabitants of the Fire. Conversely, a person may appear, in the eyes of the people, to be performing the deeds of the inhabitants of the Fire, yet he is actually among the inhabitants of Paradise. Verily, actions are judged by their final outcomes.”
