”Being satisfied and sufficed (with Allaah) opens a door of safety for the slave, and it cleanses his heart of deception, corruption and rancour. And none will be saved from the punishment of Allaah, except the one who comes to Allaah (on the Day of Judgement) with a pure heart. Likewise, there cannot be peacefulness of the heart alongside discontentment and an absence of satisfaction (with Allaah); and whenever the slave’s satisfaction (with his Lord) becomes stronger, his heart is more at peace. So malice, corruption and deception are companions of discontentment, and peacefulness, piety and sincerity of the heart are companions of satisfaction. Likewise, envy is from the fruits of discontentment and the heart’s safety from it is from the fruits of satisfaction (with Allaah).”
And Allaah knows best.
