Narrated Samura: The Prophet said, “Last night two men came to me (in a dream) and made me ascend a tree and then admitted me into a better and superior house, better of which I have never seen. One of them said, ‘This house is the house of martyrs.” (Bukhari Vol. 4, Book 52, Hadith 49)
Quran (4:95) – “Not equal are those believers who sit (at home) and receive no hurt, and those who strive and fight in the cause of Allah with their goods and their persons. Allah hath granted a grade higher to those who strive and fight with their goods and persons than to those who sit (at home). Unto all (in Faith) Hath Allah promised good: But those who strive and fight Hath He distinguished above those who sit (at home) by a special reward.”
These quotes demonstrate that jihadists, those who get killed fighting for the cause of Allah, are rewarded better than common believers who didn’t. Besides, the jihadists are forgiven all their sins and don’t have to wait in the graves until the Judgement Day, they get to Paradise immediately:
Quran (3:169-170) – “Think not of those who are slain in Allah’s way as dead. Nay, they live, finding their sustenance in the presence of their Lord; They rejoice in the bounty provided by Allah: And with regard to those left behind, who have not yet joined them (in their bliss), the (Martyrs) glory in the fact that on them is no fear, nor have they (cause to) grieve.”
So imagine: a Muslim doctor living a life of helping people, saving lives, never killing anyone, according to Islamic beliefs will wait until the Resurrection to be judged if he (or she) is worthy to receive a second-class accommodation in the Paradise.
A Palestinian teenage who stabbed a civilian Israeli and got shot by IDF, will go to Paradise immediately to receive a better reward.
I think the Islam’s priorities are clear. The reward always demonstrates importance of a deed. And this also means, that a good Muslim cannot get the better place reserved for jihadists, if there is no war between Muslims and unbelievers. That is why Islamic jihad never stops.
