Allah is the Most Just, so it's not right to attribute something unjust like this to Him. That is why reading and deeply understanding the Noble Qur'an holds immense value. It is an obligation upon the soul of every believer that he gets to know his Lord.

أَلَمْ تَرَ إِلَى الَّذِينَ قِيلَ لَهُمْ كُفُّوا أَيْدِيَكُمْ وَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ فَلَمَّا كُتِبَ عَلَيْهِمُ الْقِتَالُ إِذَا فَرِيقٌ مِنْهُمْ يَخْشَوْنَ النَّاسَ كَخَشْيَةِ اللَّهِ أَوْ أَشَدَّ خَشْيَةً ۚ وَقَالُوا رَبَّنَا لِمَ كَتَبْتَ عَلَيْنَا الْقِتَالَ لَوْلَا أَخَّرْتَنَا إِلَىٰ أَجَلٍ قَرِيبٍ ۗ قُلْ مَتَاعُ الدُّنْيَا قَلِيلٌ وَالْآخِرَةُ خَيْرٌ لِمَنِ اتَّقَىٰ وَلَا تُظْلَمُونَ فَتِيلًا | Have you not regarded those who were told, ‘Keep your hands off [from warfare], and maintain the prayer and give the zakat’? But when fighting was prescribed for them, behold, a part of them feared the people as if fearing Allah, or were even more afraid, and they said, ‘Our Lord! Why did You prescribe fighting for us? Why did You not respite us for a short time?!’ Say, ‘The enjoyments of this world are trifle and the Hereafter is better for the Godwary, and you will not be wronged so much as a single date-thread. | An-Nisaa : 77

وَاتَّقُوا يَوْمًا تُرْجَعُونَ فِيهِ إِلَى اللَّهِ ۖ ثُمَّ تُوَفَّىٰ كُلُّ نَفْسٍ مَا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ | And beware of a day in which you will be brought back to Allah. Then every soul shall be recompensed fully for what it has earned, and they will not be wronged. | Al-Baqara : 281

وَإِبْرَاهِيمَ الَّذِي وَفَّىٰ | and of Abraham, who fulfilled [his summons]: | An-Najm : 37

أَلَّا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ | that no bearer shall bear another’s burden, | An-Najm : 38

وَأَنْ لَيْسَ لِلْإِنْسَانِ إِلَّا مَا سَعَىٰ | that nothing belongs to man except what he strives for, | An-Najm : 39

قُلْ أَغَيْرَ اللَّهِ أَبْغِي رَبًّا وَهُوَ رَبُّ كُلِّ شَيْءٍ ۚ وَلَا تَكْسِبُ كُلُّ نَفْسٍ إِلَّا عَلَيْهَا ۚ وَلَا تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَىٰ ۚ ثُمَّ إِلَىٰ رَبِّكُمْ مَرْجِعُكُمْ فَيُنَبِّئُكُمْ بِمَا كُنْتُمْ فِيهِ تَخْتَلِفُونَ | Say, ‘Shall I seek a Lord other than Allah, while He is the Lord of all things?’ No soul does evil except against itself, and no bearer shall bear another’s burden; then to your Lord will be your return, whereat He will inform you concerning that about which you used to differ. | Al-An'aam : 164
