Committing suicide is a major sin according to Quran and Hadith. Paradise will be prohibited for those who commit suicide. Jundub ibn Abdullah (Ra) narrated that the Messenger of Allah (PBUH) said:
"'A man among those who came before you was wounded. He panicked and
took a knife and cut his hand, and the bleeding did not stop until he
died.' Allah, may He be glorified and exalted, said, 'My slave
hastened his death; I have forbidden Paradise to him."'
(Sahih Bukhari and Muslim)
If a person kills himself with anything in this world, Allah will punish him with the means that he used to kill him. Thaabit ibn Dahhaak (Ra) narrated that the Messenger of Allah (PBUH) said:
"Whoever kills himself with something will be punished with it on the
Day of Resurrection."
(Sahih Bukhari)
It is clearly known to us by another authentic narration that whoever commits suicide by throttling will keep on throttling himself in the Hellfire (forever) and he who commits suicide by stabbing himself will keep on stabbing himself in the Hellfire. Abu Hurayrah (Ra) narrated that the Prophet (PBUH) said:
"Whoever throws himself down from a mountain and kills himself will be
throwing himself down in the fire of hell forever and ever. Whoever
drinks poison and kills himself will be sipping it in the fire of hell
forever and ever. Whoever kills himself with a piece of iron will have
that iron in his hand, thrusting it into his belly in the fire of hell
forever and ever."
(Sahih Muslim)
Narrated by Anas Bin Malik the Prophet (PBUH) said:
"None of you should wish for death because of a calamity befalling
him; but if he has to wish for death, he should say, "O Allah! Keep me
alive as long as life is better for me, and let me die if death is
better for me."
(Sahih Bukhari Book 70 Hadith 575)
You should do your part and report such a person for nearly putting your life and people you know lives at risk. I pray Allah gives you and your family protection ameen.
