Subhanallah, this is the most profound saying I came across this year. It's by Badiuzzaman Said Nursi:
an accusation against the Divine Wisdom,
a criticism of Divine Mercy."
OMG dare you, accuse or criticize the Lord?
Worrying is tantamount to accusing and criticizing the Lord!
Allah knows best and surely He is the Best Planner and Orchestrator.
