Surah Yunus, Verse 11:
وَلَوْ يُعَجِّلُ اللَّهُ لِلنَّاسِ الشَّرَّ اسْتِعْجَالَهُم بِالْخَيْرِ لَقُضِيَ إِلَيْهِمْ أَجَلُهُمْ فَنَذَرُ الَّذِينَ لَا يَرْجُونَ لِقَاءَنَا فِي طُغْيَانِهِمْ يَعْمَهُونَ
And were Allah to hasten for mankind the evil (they invoke for themselves and for their children, etc. while in a state of anger) as He hastens for them the good (they invoke) then they would have been ruined. So We leave those who expect not their meeting with Us, in their trespasses, wandering blindly in distraction. (Tafsir At-Tabari; Vol. 11, Page 91)
Surah At-Taubah, Verse 55:
So let not their wealth or their children amaze you (O Muhammad SAW); in reality Allah’s Plan is to punish them with these things in the life of the this world, and that their souls shall depart (die) while they are disbelievers.
Surah Al-Anfal, Verse 73:
And those who disbelieve are allies to one another, (and) if you (Muslims of the whole world collectively) do not do so (i.e. become allies, as one united block with one Khalifah – chief Muslim ruler for the whole Muslim world to make victorious Allah’s Religion of Islamic Monotheism), there will be Fitnah (wars, battles, polytheism, etc.) and oppression on earth, and a great mischief and corruption (appearance of polytheism).
O you who believe! If you obey and fear Allah, He will grant you Furqan a criterion (to judge between right and wrong), or (Makhraj, i.e. making a way for you to get out from every difficulty)
Surah Al-Anfal, Verse 29:
O you who believe! If you obey and fear Allah, He will grant you Furqan a criterion [(to judge between right and wrong), or (Makhraj, i.e. making a way for you to get out from every difficulty)], and will expiate for you your sins, and forgive you, and Allah is the Owner of the Great Bounty.
And know that your possessions and your children are but a trial and that surely with Allah is a mighty reward
Surah Al-Anfal, Verse 28:
And know that your possessions and your children are but a trial and that surely with Allah is a mighty reward.
Surah Al-Anfal, Verse 25:
وَاتَّقُوا فِتْنَةً لَّا تُصِيبَنَّ الَّذِينَ ظَلَمُوا مِنكُمْ خَاصَّةً وَاعْلَمُوا أَنَّ اللَّهَ شَدِيدُ الْعِقَابِ
And fear the Fitnah (affliction and trial, etc.) which affects not in particular (only) those of you who do wrong (but it may afflict all the good and the bad people), and know that Allah is Severe in punishment.
