The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Truly, whoever takes the Hereafter as his (primary) concern, Allah places his richness before his eyes (his heart feels content), gathers his inner self (so he is at peace with himself), and this worldly life comes to him with compliance. And whoever has this worldly life as his (main) concern, Allah makes his poverty appear imminent to him, disunites his inner self (so he feels disgruntled and unhappy) and he does not gain anything from this worldly life except what had been destined for him.” [Tirmidhi]
A boat needs water to go places: Allah (subhana wa ta’ala) made the things of this world for you to use. But when water enters the boat it sinks: Don't let the love of worldly things enter your heart or it will sink you.
How can one decrease one’s concern for this world? When you talk less about something its importance begins to decrease in your eyes. So try not to talk about the things that are not an Akhirah seeker’s primary concern.
