Why Does God Allow Hardship?

[8:29] O you who believe, if you reverence GOD, He will enlighten you, remit your sins, and forgive you. GOD possesses infinite grace.Jeremiah 29:11For surely I know the plans I have for you, says the Lord, plans to prosper you and not for harm you, to give you a future with hope.[6:132] Everyone will attain a rank commensurate with their deeds. Your Lord is never unaware of anything they do.
