আল্লাহ কেন মন্দ ও দুঃখ-কষ্ট ঘটতে দেন?

ٱلَّذِي خَلَقَ ٱلۡمَوۡتَ وَٱلۡحَيَوٰةَ لِيَبۡلُوَكُمۡ أَيُّكُمۡ أَحۡسَنُ عَمَلٗاۚ وَهُوَ ٱلۡعَزِيزُ ٱلۡغَفُورُ

[He] who created death and life to test you [as to] which of you is best in deed - and He is the Exalted in Might, the Forgiving -

وَلَنَبۡلُوَنَّكُم بِشَيۡءٖ مِّنَ ٱلۡخَوۡفِ وَٱلۡجُوعِ وَنَقۡصٖ مِّنَ ٱلۡأَمۡوَٰلِ وَٱلۡأَنفُسِ وَٱلثَّمَرَٰتِۗ وَبَشِّرِ ٱلصَّٰبِرِينَ ٱلَّذِينَ إِذَآ أَصَٰبَتۡهُم مُّصِيبَةٞ قَالُوٓاْ إِنَّا لِلَّهِ وَإِنَّآ إِلَيۡهِ رَٰجِعُونَ أُوْلَٰٓئِكَ عَلَيۡهِمۡ صَلَوَٰتٞ مِّن رَّبِّهِمۡ وَرَحۡمَةٞۖ وَأُوْلَٰٓئِكَ هُمُ ٱلۡمُهۡتَدُونَ

And We will surely test you with something of fear and hunger and a loss of wealth and lives and fruits, but give good tidings to the patient, Who, when disaster strikes them, say, "Indeed we belong to Allāh, and indeed to Him we will return." Those are the ones upon whom are blessings from their Lord and mercy. And it is those who are the [rightly] guided.
