وَعَنْ جُنْدُبِ بْنِ عَبْدُ اللَّهِ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " كَانَ فِيمَنْ كَانَ قَبْلَكُمْ رَجُلٌ بِهِ جُرْحٌ فجزِعَ فأخذَ سكيّناً فحزَّ بِهَا يَدَهُ فَمَا رَقَأَ الدَّمُ حَتَّى مَاتَ قَالَ اللَّهُ تَعَالَى: بَادَرَنِي عَبْدِي بِنَفْسِهِ فَحَرَّمْتُ عَلَيْهِ الْجنَّة "

Jundub b. ‘Abdallah reported God’s Messenger as saying that among those who lived before their time there was a man who had a wound and had so little patience to bear it that he took a knife with which he cut off his hand, but the blood did not cease to flow till he died. God most high said, “My servant has tried to outstrip me in taking his life, so I have excluded him from paradise.” (Bukhari and Muslim.)
