Beautiful Hadith on this Life and Hereafter

Zaid ibn Thabit reported: I heard the Messenger of Allah, peace and blessings be upon him, say, “Whoever makes the world his most important matter, Allah will confound his affairs and make poverty appear before his eyes and he will not get anything from the world except what has been decreed for him. Whoever makes the Hereafter his most important matter, Allah will settle his affairs and make him content in his heart and the world will come to him although he does not want it.”

Umar ibn Abdul Aziz, may Allah have mercy on him, said, “Take care of your Hereafter and Allah will take care of your worldly life. Take care of your private life and Allah will take care of your public life.”

عن زيد بن ثابت قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ كَانَتْ الدُّنْيَا هَمَّهُ فَرَّقَ اللَّهُ عَلَيْهِ أَمْرَهُ وَجَعَلَ فَقْرَهُ بَيْنَ عَيْنَيْهِ وَلَمْ يَأْتِهِ مِنْ الدُّنْيَا إِلَّا مَا كُتِبَ لَهُ وَمَنْ كَانَتْ الْآخِرَةُ نِيَّتَهُ جَمَعَ اللَّهُ لَهُ أَمْرَهُ وَجَعَلَ غِنَاهُ فِي قَلْبِهِ وَأَتَتْهُ الدُّنْيَا وَهِيَ رَاغِمَةٌ
