Saʿd used to teach his sons the following words as a teacher teaches his students the skill of writing and used to say that Messenger of Allah ﷺ used to seek Refuge with Allah from them (i.e. the evils) at the end of every prayer. The words are: 'O Allah! I seek refuge with You from cowardice, and seek refuge with You from being brought back to a bad stage of old life and seek refuge with You from the afflictions of the world, and seek refuge with You from the punishments in the grave.'  

كَانَ سَعْدٌ يُعَلِّمُ بَنِيهِ هَؤُلاَءِ الْكَلِمَاتِ كَمَا يُعَلِّمُ الْمُعَلِّمُ الْغِلْمَانَ الْكِتَابَةَ وَيَقُولُ إِنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَتَعَوَّذُ مِنْهُنَّ دُبُرَ الصَّلاَةِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْجُبْنِ وَأَعُوذُ بِكَ أَنْ أُرَدَّ إِلَى أَرْذَلِ الْعُمُرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الدُّنْيَا وَأَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ فَحَدَّثْتُ بِهِ مُصْعَبًا فَصَدَّقَهُ  

The Prophet ﷺ used to say, "O Allah! I seek refuge with You from helplessness, laziness, cowardice and feeble old age; I seek refuge with You from afflictions of life and death and seek refuge with You from the punishment in the grave."  

كَانَ النَّبِيُّ ﷺ يَقُولُ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْعَجْزِ وَالْكَسَلِ وَالْجُبْنِ وَالْهَرَمِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ وَأَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ
