you are asking about“suicide bombers”. Islam’s stand on the two concepts here “suicide” and ‘martyrdom’. It has become crystal clear that suicide is forbidden, killing innocent civilians is forbidden. as Quran Says
Spend your wealth in the Way of Allah and do not throw yourselves with your own hands into destruction. You shall be charitable; GOD loves the charitable.(2:195)
But this should not be confused with causing one’s own death during resisting aggression and injustice (( Palestinian acts of resistance)); a clear line should be drawn here.
Islam condemns suicide as much as it condemns oppression and aggression against others. While the Muslims are commanded to stand for their rights and defend themselves, their properties and their freedom.anyone who causes his own death in the cause of resisting aggression, defending his own (or others’) property and dignity ( Palestinian acts of resistance), will be deemed as dying in the noble cause of upholding truth and justice. In other words, his death has to do with ‘justice’. Hence, it’s logical for such person to be redeemed in the Hereafter, under the same ‘justice’ and be admitted to Paradise, dwelling there forever.
