I said the materialist will not accept the explanation: that God Himself punishes people by many ways: one of such ways is the conflicts, wars and fighting.
Such punishment is directed towards the idolaters, atheists and enthusiastic about the prophets and saints.
This punishment will include the monotheists and righteous people: in case they do not reject the idolatry and blasphemy and the wrong-doing of people --> so in such case these will be included in the punishment which will be general and not confined to disbelievers alone.
But in case the believers and the exclusive devotees to God alone; if these forbid the wrong-doing and the blasphemy and the association of patrons with God --> then they may be saved and not included in the punishment.
A tyrant may be set on people to oppress them, and the unjustice and mess will be some kind of punishment.
Of course, the materialist who do not believe in God, and who do not believe in God alone without any patron or son --> such will not believe in the decree of God Almighty.
I explained this before, but most of them do not understand or do not want to understand.
So if you don't believe in the Quran, then refer to your Torah and Gospel.
Refer to the chapter 26 in the Book of Levites or Priests.
Douay-Rheims Catholic Bible, Book Of Leviticus Chapter 26
And in the Quran 2: 235
تِلْكَ الرُّسُلُ فَضَّلْنَا بَعْضَهُمْ عَلَى بَعْضٍ مِّنْهُم مَّن كَلَّمَ اللّهُ وَرَفَعَ بَعْضَهُمْ دَرَجَاتٍ وَآتَيْنَا عِيسَى ابْنَ مَرْيَمَ الْبَيِّنَاتِ وَأَيَّدْنَاهُ بِرُوحِ الْقُدُسِ وَلَوْ شَاء اللّهُ مَا اقْتَتَلَ الَّذِينَ مِن بَعْدِهِم مِّن بَعْدِ مَا جَاءتْهُمُ الْبَيِّنَاتُ وَلَكِنِ اخْتَلَفُواْ فَمِنْهُم مَّنْ آمَنَ وَمِنْهُم مَّن كَفَرَ وَلَوْ شَاء اللّهُ مَا اقْتَتَلُواْ وَلَكِنَّ اللّهَ يَفْعَلُ مَا يُرِيدُ
The explanation:
(
These [tales of the] apostles [: messengers, We relate to you, Mohammed; of whom] did We prefer some above others [by specifying him with special criteria.]
Among them was [Moses] to whom God spoke [in the valley of Sinai],
and another one [: Idries: Elia] We raised [to certain high] degrees [of honor],
and We gave to Jesus, the son of Mary, the manifest [miraculous] signs and We aided him by [Gabriel:] the Holy Spirit.
Had God willed, then the [people] after these [apostles] would not have fought with each other, even after manifest signs [of revelation] had come to them [included in the heavenly scriptures.]
But they varied: some [steadfastly] believed and others disbelieved.
Had God willed, then they would not have fought each other, but God does whatever He wills.)
