As far as I searched, it has mentioned approximately 10 items in regard to repelling and defense which seems four of them are related to the military defense. Of course apparently it has not mentioned directly regarding self-defense, but anyhow it could be inferred from the text that it is people obligation to do it in some ways.
فَهَزَمُوهُم بِإِذْنِ اللَّـهِ وَقَتَلَ دَاوُودُ جَالُوتَ وَآتَاهُ
اللَّـهُ الْمُلْكَ وَالْحِكْمَةَ وَعَلَّمَهُ مِمَّا يَشَاءُ ۗ
وَلَوْلَا دَفْعُ اللَّـهِ النَّاسَ بَعْضَهُم بِبَعْضٍ لَّفَسَدَتِ
الْأَرْضُ وَلَـٰكِنَّ اللَّـهَ ذُو فَضْلٍ عَلَى الْعَالَمِينَ ﴿٢٥١﴾
So they defeated them by permission of Allah, and David killed
Goliath, and Allah gave him the kingship and prophethood and taught
him from that which He willed. And if it were not for Allah checking(repelling)
[some] people by means of others, the earth would have been corrupted,
but Allah is full of bounty to the worlds. (251)(al-Baqarah:251)
Consequently, it indicates that the world would be destroyed in case that defending was wrong. On the other hand, self-defense could be compared with defending against cruel people or thief or so on which has indicated in plural item in Quran. And actually it could not be logical saying we ought not to do self-defense since it has mentioned in plural case.
On the other hand, it is inferred from the narrations and the words of the scholars that:
- It is permissible for any person protecting his/her family and
- Defending has many degrees and in case that the one option left is to
kill the transgressor, this is permissible to do like that. In such a
position, the murderer is not required to pay blood money and Qisas
will not be carried out. However, in regard to the loss of wealth in
particular, the Imams have instructed us not to kill anyone. For
example, it is haram to kill a thief that is running away with one’s
- If someone is killed while defending himself/herself, he is
considered as a martyr.
- Proving that one was defending himself is a different issue from it
being permissible, meaning that proving it requires adequate
In any event, there would be many other situations that ought to be observed in that case. What we have done is only mention the general points that are applicable to everybody.
In regard to the last part of your inquiry that was inquired will Allah punish... , I couldn't find the precise issue, but as a rational rule and also whereof it is Wajib for the humans to protects their body, we can infer that Allah will punish us in case that we did not protect ourselves. How come? Since in truth, our bodies are consignments which are Allah's in fact.
Eventually, as the last part of my speech, I should mention a significant point which is concerning Quran. Actually we should not assume that the holy Quran declared everything in details. Occasionally it declared some issues in general and occasionally mentioned some matters by details. Consequently we ought to pay attention that we cannot deny whatever has not come in Quran directly. Since for instance it has not come Quran that why Salah-al-Soboh is 2Rak'ahs and so forth. Then some other issues have come in hadiths (traditions) and some other matters could be considered logically and rationally. Good luck.
