I heard Messenger of Allah ﷺ saying, "The heart of an old man remains young in two respects, i.e., his love for the world (its wealth, amusements and luxuries) and his incessant hope."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺيَقُولُ: «لاَ يَزَالُ قَلْبُ الْكَبِيرِ شَابًّا فِي اثْنَتَيْنِ: فِي حُبِّ الدُّنْيَا، وَطُولِ الأَمَلِ۔»  

Messenger of Allah ﷺ said, "The son of Adam (i.e. man) grows old and so also two (desires) grow old with him, i.e., love for wealth and (a wish for) a long life."  

قَالَ رَسُولُ اللَّهِ ﷺ يَكْبَرُ ابْنُ آدَمَ وَيَكْبَرُ مَعَهُ اثْنَانِ حُبُّ الْمَالِ وَطُولُ الْعُمُرِ رَوَاهُ شُعْبَةُ عَنْ قَتَادَةَ
