Peace to one and all,
Contentment with the Decree of Allah, Azzah Wa Jallah, is one of the acts of worship of the heart. The Prophet, peace be upon him, said: "He has tasted the sweetness of faith: he who is content with Allah as his Lord, Islam as his religion, and Muhammad as his Prophet." [Muslim].

We must know that Allah ( Almighty and Glorified is He ) had portioned for us... for each one... our provision. As long as we work, we get what is written for us. In this regard, the Prophet, peace be upon him, said:- "Know that even if the whole of community were to gather together to benefit with something, they would not benefot you with anything except that which Allah has already recorded for you, and that if they gather together to harm you with something, they would not be able to harm you with anything except that which Allah has already recorded against you." [Tirmidhi].

Knowing this should empower us, because we thereby know that everything that hapens is by the permission of Allah. This should not prevent us from reflecting and trying to figure out how our actions played a role, but learning from an experience is part of Contentment... because you trust that Allah, Azzah Wa Jallah, is teaching you a lesson through trial.
