Don't be Sad
Take your precautions
In all facets of life, one should take precautions and study the possible outcomes of every action, because by being careful, one will have no cause for future self-recrimination. If the results of one’s endeavors are good, one should thank and praise Allah. If the results of one’s endeavors are not so good, one should say, “Allah has made His decree and whatever He pleases, He does."
