Why do some people die early while others live long, and how does God hold accountable those who die early, and is there justice in the early death of those who commit evil, even though they might have repented if they had been granted a longer life?

For a servant's faith to be sound, he must believe in God's absolute perfection and uniqueness in His command and creation. He is the Creator and Disposer of all things with wisdom and mercy, and He is not questioned about what He does due to the perfection of His knowledge and power. He must also affirm that God wrongs no one; rather, all His actions are good, and people are the ones who wrong themselves. As for doubts concerning the fate of those who died young or others, these are satanic whispers. God knows best the ultimate destiny of His creation, and His proof against them is conclusive. They will confess their sins on the Day of Resurrection. One must seek refuge from the whispers of Satan and cling firmly to God.
