Are the prophets infallible, and how do divine justice reconcile with the differences among creatures, the existence of calamities and disasters, eternal torment, and the termination of human life after its creation?

The infallibility of prophets in conveying messages from Allah is a matter of consensus, with disagreement only concerning their infallibility from minor sins and some major sins. The issue of divine justice should not be delved into by a rational person, for Allah is the Wisest of judges, and He is not questioned about what He does. He has forbidden injustice upon Himself, and the owner's disposal of his property is just. A Muslim must be content with Allah's decree and destiny. The variation in the sizes of things and the diversity of desires within them hold many benefits, including the exchange of benefits and the prevention of conflict. Trials do not contradict justice; they are either for raising ranks or expiating sins. The sin of polytheism (shirk (definition)) is the only one that necessitates eternal damnation in Hellfire. Allah's causing people to die and then resurrecting them is a test to see which of them is best in deeds, and by their death, they transition from a transient abode to an enduring one.
