"‏ مَنْ كَانَتِ الدُّنْيَا هَمَّهُ فَرَّقَ اللَّهُ عَلَيْهِ أَمْرَهُ وَجَعَلَ فَقْرَهُ بَيْنَ عَيْنَيْهِ وَلَمْ يَأْتِهِ مِنَ الدُّنْيَا إِلاَّ مَا كُتِبَ لَهُ وَمَنْ كَانَتِ الآخِرَةُ نِيَّتَهُ جَمَعَ اللَّهُ لَهُ أَمْرَهُ وَجَعَلَ غِنَاهُ فِي قَلْبِهِ وَأَتَتْهُ الدُّنْيَا وَهِيَ رَاغِمَةٌ ‏"

“Zaid bin Thabit departed from Marwan at mid-day. I said: ‘He has not sent him out at this time of the day except for something he asked.’ So I asked him, and he said: ‘He asked me about some things we heard from the Messenger of Allah (ﷺ) say: “Whoever is focused only on this world, Allah will confound his affairs and make him fear poverty constantly, and he will not get anything of this world except that which has been decreed for him. Whoever is focused on the Hereafter, Allah will settle his affairs for him and make him feel content with his lot, and his provision and worldly gains will undoubtedly come to him.”
