"Mu'awiyah came to Abu Hashim bin 'Uthbah to visit him when he was ill (and dying). He said: 'O Uncle! Why do you cry? Is it from the pangs of death or desire for this world?' He said: 'Neither of these. But the Messenger of Allah ﷺ had commissioned me with an obligation that I did not abide by. He ﷺ said: "It suffices you to gather the wealth of a servant or a rider in the cause of Allah." And (it is only) today I find that I have gathered it.'" (Using translation from Tirmidhī 2327)
يَا خَالُ مَا يُبْكِيكَ؟ أَوَجَعٌ يَشْمَئِزُّكَ؟ أَمْ حِرْصٌ عَلَى الدُّنْيَا؟ قَالَ كُلٌّ لَا وَلَكِنَّ رَسُولَ اللهِ ﷺ عَهِدَ إِلَيَّ عَهْدًا لَمْ آخُذْ بِهِ فَقَالَ «يَا أَبَا هَاشِمٍ سَتَرَى أَمْوَالًا يُؤْتَاهَا أَقْوَامٌ وَإِنَّمَا يَكْفِيكَ مِنْ جَمِيعِ الدُّنْيَا خَادِمٌ وَمَرْكَبٌ فِي سَبِيلِ اللهِ» فَأَرَانِيَ الْيَوْمَ قَدْ جَمَعْتُ
