Suicide is the act of a person or group of people to stop a heartbeat that results in the end of life in the world.
Regarding suicide, Allah swt. has said in the Qur'an in the letter of An-Nisa verse 29-30 which reads:
وَلَا تَقۡتُلُوٓاْ أَنفُسَكُمۡۚ إِنَّ ٱللَّهَ كَانَ بِكُمۡ رَحِيمٗا. وَمَن يَفۡعَلۡ ذَٰلِكَ عُدۡوَٰنٗا وَظُلۡمٗا فَسَوۡفَ نُصۡلِيهِ نَارٗاۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًا
Meaning : And do not kill yourself; Allah is Most Merciful to you. and whoever does so violates the rights and persecutions, then We will put him in hell. That is easy for God. (Surah An-Nisa ': 29-30).
Interpreting the above verse, most of the scholars, Ibn Abbas, Al-Wahidiy explain the purpose of "and do not kill you", interpreting that it is not some of you killing some others or in other words killing each other, because we are followers of one religion and we are like one body.
While some other scholars argue that what is meant by "and do not you kill yourself" is to kill yourself or in a word that short of suicide.
So with the statement of An-Nisa, Verses 29-30, suffice as proof that suicide is forbidden in Islam, why is it enough with the statement of one verse? ... because there is no Qur'anic verse that argues against each other.
Bom Bunuh Diri/Suicide Bomb
For Muslims who are in the area of conflicts where their worship, scripture, self and family are in their worst state, they wear bombs on their bodies and throw themselves into the crowd of those who embraced them to kill some of them. This kind of act is permissible and God willing, the culprit gets a martyr's reward..*
وَأَعِدُّوا لَهُمْ مَا اسْتَطَعْتُمْ مِنْ قُوَّةٍ وَمِنْ رِبَاطِ الْخَيْلِ تُرْهِبُونَ بِهِ عَدُوَّ اللَّهِ وَعَدُوَّكُمْ
"Dan siapkanlah untuk menghadapi mereka kekuatan apa saja yang kamu sanggupi dan dari kuda-kuda yang ditambat untuk berperang (yang dengan persiapan itu) kamu menggentarkan musuh Allah dan musuhmu” (QS. Al Anfal: 60).
"And prepare to face them whatever powers you can afford and from the horses that are moored for battle (which by that preparation) you are frightening the enemy of Allah and your enemy" (Surat al-Anfal: 60).
So the form of threat of fear to such enemies of God is included in the meaning of this glorious verse.
And first the Muslims while fighting against their kuffar troops entered the middle of the line of kuffar troops carrying swords. The Muslims knew that the enemy's sword could kill him but before he was killed he could kill some and injure some of it.
Likewise, people who use bombs in the body and then enter the ranks of enemies so that users of this bomb are killed and the enemy is also killed. And may he be among the martyrs whom God says about them.
Bom bunuh diri menjadi haram/Suicide bombing be forbidden
Nabi Muhammada sallallaahu 'alaihi wa sallam said, "Whoever commits suicide by using a means in the world, then he will be tortured in that way on the Day of Judgment." (Narrated by Bukhari and Muslim).
As for the unintentional suicide then it is given udzur and the culprit is innocent based on the word of Allah 'azza wa jalla (which means), "And there is no sin for you guilty of wrongdoing but (sin) is you deliberate from your heart. "(Surah Al-Ahzab: 5).
Thus the suicide bombing carried out by some people in the name of jihad is an aberration (read: the violation of shari'ah).
Apalagi dengan aksi itu menyebabkan terbunuhnya kaum muslimin atau orang kafir yang tidak memberi mudharat atau memusuhi kaum muslimin tanpa alasan yang dibenarkan syari’at.
Moreover, with the action that led to the killing of Muslims or unbelievers who do not give mudharat or hostile to the Muslims for no reason justified shari'ah.
So Islam is not a religion that justifies terror, jihad for no reason by religious law and kills without rights.
