Sunan Ibn Majah Book 37, Hadith 4103

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، أَنْبَأَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ سَمُرَةَ بْنِ سَهْمٍ، - رَجُلٌ مِنْ قَوْمِهِ - قَالَ نَزَلْتُ عَلَى أَبِي هَاشِمِ بْنِ عُتْبَةَ وَهُوَ طَعِينٌ فَأَتَاهُ مُعَاوِيَةُ يَعُودُهُ فَبَكَى أَبُو هَاشِمٍ فَقَالَ مُعَاوِيَةُ مَا يُبْكِيكَ أَىْ خَالِ أَوَجَعٌ يُشْئِزُكَ أَمْ عَلَى الدُّنْيَا فَقَدْ ذَهَبَ صَفْوُهَا قَالَ عَلَى كُلٍّ لاَ وَلَكِنْ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ عَهِدَ إِلَىَّ عَهْدًا وَدِدْتُ أَنِّي كُنْتُ تَبِعْتُهُ قَالَ ‏ "‏ إِنَّكَ لَعَلَّكَ تُدْرِكُ أَمْوَالاً تُقْسَمُ بَيْنَ أَقْوَامٍ وَإِنَّمَا يَكْفِيكَ مِنْ ذَلِكَ خَادِمٌ وَمَرْكَبٌ فِي سَبِيلِ اللَّهِ ‏"‏ ‏.‏ فَأَدْرَكْتُ فَجَمَعْتُ ‏.‏

It was narrated from Abu Wa’il that a man from his people – Samurah bin Sahm – said:“We stopped with Abu Hashim bin ‘Utbah, who had been stabbed, and Mu’awiyah came to visit him. Abu Hashim wept and Mu’awiyah said to him: ‘Why are you weeping, O maternal uncle? Is there some pain bothering you, or is it because of this world, the best of which has already passed?’ He said: ‘It is not for any of these reasons. But the Messenger of Allah (ﷺ) gave me some advice and I wish that I had followed it. He (ﷺ) said: “There may come a time when you will see wealth divided among the people, and all you will need of that is a servant and a mount to ride in the cause of Allah.” That time came, but I accumulated wealth.’”
