وَيُضِلُّ اللَّهُ الظَّالِمِينَAnd Allah misguides those who knowingly do evil. [Quran, 14:27]
This was somewhat of a surprise to me. Doesn't Allah always push humans toward what's good, right, and just? Apparently not.
To understand this verse better, let's look at what comes before it:
يُثَبِّتُ اللَّهُ الَّذِينَ آَمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآَخِرَةِGod will make the believers firm (on their beliefs) in this life and the next by the help of God's enduring words. [Quran, 14:27]
In other words, depending on a person's choices, God may either choose to guide the person toward a better future, or toward a worse future.
God reserves the right to be a bad influence on people who God deems deserving of it.
