the Messenger of Allah ﷺ said: "Whosoever makes all ˹his˺ concerns into one concern (meaning, the concern of the Hereafter), Allah will relieve him of ˹all˺ concerns of his world. And whosoever is indulged ˹only˺ in concerns ˹of this world˺, Allah will not care in which of the valleys of this world he dies." (Using translation from Ḥākim 3658)
قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ جَعَلَ الْهُمُومَ هَمًّا وَاحِدًا كَفَاهُ اللَّهُ مَا هَمَّهُ مِنْ أَمْرِ الدُّنْيَا وَالْآخِرَةِ وَمَنْ تَشَاعَبَتْ بِهِ الْهُمُومُ لَمْ يُبَالِ اللَّهُ فِي أَيِّ أَوْدِيَةِ الدُّنْيَا هَلَكَ»
