[Machine] There was a man with the Messenger of Allah ﷺ in some of his expeditions. He faced a severe trial but Muslim astonishment at his trial. The Messenger of Allah ﷺ said: "Indeed, he is from the people of Hell." We said, "He was fighting in the cause of Allah with the Messenger of Allah. Allah and His Messenger know best." He then inflicted a wound upon himself, and when the wound worsened, he placed his sword between his chest and leaned on it. The Messenger of Allah ﷺ was informed about the man and it was said to him, "The man whom you said what you said about, I have seen him taking his own life while the sword is between his chest." The Prophet ﷺ said: "Verily, the man is doing the deeds of the people of Paradise while it appears to people that he is doing the deeds of the people of Hell. Verily, he is one of the people of Paradise."  

أحمد:٢٢٨١٣ – حَدَّثَنَا أَبُو النَّضْرِ حَدَّثَنَا عَبْدُ الرَّحْمَنِ يَعْنِي ابْنَ عَبْدِ اللهِ بْنِ دِينَارٍ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ

كَانَ مَعَ رَسُولِ اللهِ ﷺ رَجُلٌ فِي بَعْضِ مَغَازِيهِ فَأَبْلَى بَلَاءً حَسَنًا فَعَجِبَ الْمُسْلِمُونَ مِنْ بَلَائِهِ فَقَالَ رَسُولُ اللهِ ﷺ أَمَا إِنَّهُ مِنْ أَهْلِ النَّارِ قُلْنَا فِي سَبِيلِ اللهِ مَعَ رَسُولِ اللهِ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَجَرَحَ الرَّجُلُ فَلَمَّا اشْتَدَّتْ بِهِ الْجِرَاحُ وَضَعَ ذُبَابَ سَيْفِهِ بَيْنَ ثَدْيَيْهِ ثُمَّ اتَّكَأَ عَلَيْهِ فَأُتِيَ رَسُولُ اللهِ ﷺ فَقِيلَ لَهُ الرَّجُلُ الَّذِي قُلْتَ لَهُ مَا قُلْتَ قَدْ رَأَيْتُهُ يَتَضَرَّبُ وَالسَّيْفُ بَيْنَ أَضْعَافِهِ فَقَالَ النَّبِيُّ ﷺ إِنَّ الرَّجُلَ لَيَعْمَلُ بِعَمَلِ أَهْلِ الْجَنَّةِ فِيمَا يَبْدُوَ لِلنَّاسِ وَإِنَّهُ لَمِنْ أَهْلِ النَّارِ وَإِنَّهُ لَيَعْمَلُ عَمَلَ أَهْلِ النَّارِ فِيمَا يَبْدُو لِلنَّاسِ وَإِنَّهُ لَمِنْ أَهْلِ الْجَنَّةِ

bukhari:4207 – ʿAbdullāh b. Maslamah > Ibn Abū Ḥāzim from his father > Sahl

During one of his Ghazawat, the Prophet ﷺ encountered the pagans, and the two armies fought, and then each of them returned to their army camps. Amongst the (army of the) Muslims there was a man who would follow every pagan separated from the army and strike him with his sword. It was said, "O Messenger of Allah ﷺ! None has fought so satisfactorily as so-and-so (namely, that brave Muslim). "The Prophet said, "He is from the dwellers of the Hell-Fire." The people said, "Who amongst us will be of the dwellers of Paradise if this (man) is from the dwellers of the Hell-Fire?" Then a man from amongst the people said, "I will follow him and accompany him in his fast and slow movements." The (brave) man got wounded, and wanting to die at once, he put the handle of his sword on the ground and its tip in between his breasts, and then threw himself over it, committing suicide. Then the man (who had watched the deceased) returned to the Prophet ﷺ and said, "I testify that you are Apostle of Allah." The Prophet ﷺ said, "What is this?" The man told him the whole story. The Prophet ﷺ said, "A man may do what may seem to the people as the deeds of the dwellers of Paradise, but he is of the dwellers of the Hell-Fire and a man may do what may seem to the people as the deeds of the dwellers of the Hell-Fire, but he is from the dwellers of Paradise."
