Hadith on Suicide: Man kills himself and loses Paradise

Jundub reported: The Messenger of Allah, peace and blessings be upon him, said, “A man among those before you was wounded. He was in such anguish that he took a knife, slit his wrist, and let the blood flow until he died. Allah Almighty said: My servant has preceded me with his soul, so I have forbidden Paradise for him.

عن جُنْدُب قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ فِيمَنْ كَانَ قَبْلَكُمْ رَجُلٌ بِهِ جُرْحٌ فَجَزِعَ فَأَخَذَ سِكِّينًا فَحَزَّ بِهَا يَدَهُ فَمَا رَقَأَ الدَّمُ حَتَّى مَاتَ قَالَ اللَّهُ تَعَالَى بَادَرَنِي عَبْدِي بِنَفْسِهِ حَرَّمْتُ عَلَيْهِ الْجَنَّةَ
