God is cruel.

Some people allege that God is a stern and cruel God who demands to be obeyed fully. He is not loving and kind. Nothing can be farther from truth than this allegation. God is more loving and kinder than a mother to her dear child. God is the one who has given you life and has given you hands, legs, ears, and all your other body parts. You should be thankful and you should know that he can take it all away with death. God is also Just. Hence evildoers and sinners must have their share of punishment and the virtuous, His bounties and favors. Actually God's attribute of Mercy has full manifestation in His attribute of Justice. People suffering throughout their lives for His sake and people oppressing and exploiting other people all their lives should not receive similar treatment from their Lord. Expecting similar treatment for them will amount to negating the very belief in the accountability of man in the Hereafter and thereby negating all the incentives for a moral and virtuous life in this world. The Creator must be of a different nature from the things created because if he is of the same nature as they are, he will be temporal and will therefore need a maker. It follows that nothing is like Him. If the maker is not temporal, then he must be eternal. But if he is eternal, he cannot be caused, and if nothing outside him causes him to continue to exist, which means that he must be self-sufficient. And if the does not depend on anything for the continuance of his own existence, then this existence can have no end. The Creator is therefore eternal and everlasting: He is the First and the Last. He is Self-Sufficient and he does not create only in the sense of bringing things into being, He also preserves them and takes them out of existence and is the ultimate cause of whatever happens to them. God tells us He is Pure, Loving, and absolutely Just in every respect. He says He is the Best of Judges. He also tells us the life we are in here is a test. He has created everything existing and He created whatever happens as well. There is nothing in this existence except what He has created. He also says He created evil (although He is not evil). He is using this as one of the many tests for us. Consider people who do so much evil in the earth and then live to a ripe old age in the splendor and wealth of their ill-gotten gains and die without ever being taken to task for their deeds. Where is the justice or fairness in this? Reward and punishment are definitely a part of the Next Life on a very permanent basis. Those who suffer in this life and seemly have nothing to show for all their hard works, good deeds and sacrifices and maintaining the faith can look forward to a far greater reward in a place where these things will not be temporary but rather they will be for eternity. Those who corrupt, violate, injure and do evil and destruction seem to escape any justice here, yet in the Next Life they too will see the fruits of their labors, and certainly they will be paid according to what they have done as well. As regards oppression, this is something God forbids for Himself to do to anyone and He hates it when anyone oppresses someone else. He does have absolute power over everything. He allows sickness, disease, death and even oppression so we can all be tested in what we do. Without evil, how can we measure good? When God created, he created its opposites so we can compare and reflect on what is right.
