عَنْ شَدَّادِ بْنِ أَوْسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْكَيِّسُ مَنْ دَانَ نَفْسَهُ وَعَمِلَ لِمَا بَعْدَ الْمَوْتِ وَالْعَاجِزُ مَنِ اتَّبَعَ نَفْسَهُ هَوَاهَا وَتَمَنَّى عَلَى اللَّهِ
It is narrated from Sayyiduna Shaddad bin Aws (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The intelligent one is he who humbles his soul and acts for what is after death, and the incapable and helpless one is he who lets his soul follow its desires and merely wishes upon Allah.
