Whoever makes the Aakhirah his concern, Allah will gather together his affairs, place contentment in his heart and the world will come to him despite his reluctance. And whoever makes the Dunya his concern, Allah will scatter his affairs, put poverty before him and nothing of the world will come to him except what Allah has written for him.

The prophet (Salla-Allaahu ‘alaihi wa sallam) [Reported by At-Tirmidhee and authenticated by Al-Albani]
