Q: Allah Ta'ala says in the holy quran "In order that you may not grieve at the things that you fail to get, nor rejoice over that which has been given to you. And Allah like not prideful boasters" Sura hadeed ayah 23
My question is that sometimes we lose or fail to get something because of our wrong choices or decisions (we make these wrong choices by mistake, carelessness, not judging the matter judiciously or out of arrogance or ignorance). We turn out to be loser (ok this was written in our destiny) but should we not grieve if we made a wrong choice? Are we not responsible for what is written in our destiny? Allah is just so how can he make one's destiny good and other's bad. It is also said that everything happens for good. Is it applicable in the case we made a wrong choice? So should we not grieve for our bad choices in life?
