Sheikh ‘Abdul-‘Azeez ar-Raajhee, may Allaah preserve him, said,

‘Yes, this is not something which it is proper for an individual to do, because this world is something which is passing and temporary in nature. It is not right that a person become distressed due to affairs of this world, nor that they become his reason for happiness and joy. Rather an individual’s happiness or sadness should be connected to the state of his religion and connected to his religious life. It should come about due to the state of his way of life and religion.
He becomes pleased and happy with the blessing of Allaah upon him in his learning knowledge through the Qur’aan, and by his being granted success to put forth righteous deeds. Likewise becoming saddened by his sins and transgressing within his religion. And Allaah the Most High said: Say: ﴾In the Bounty of Allaah, and in His Mercy (i.e. Islaam and the Qur’aan); -therein let them rejoice.” That is better than what (the wealth) they amass.﴿-(Surah Yunus: 58)”’
