Saʿd bin Abi Waqqas used to recommend these five (statements) and say that the Prophet ﷺ said so (and they are): "O Allah! I seek refuge with You from miserliness, and seek refuge with You from cowardice, and seek refuge with You from being brought back to geriatric old age, and seek refuge with You from the afflictions of the world, and seek refuge with You from the punishment of the grave." (Using translation from Bukhārī 6370)  

عَنِ النَّبِيِّ ﷺ «اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْبُخْلِ وَأَعُوذُ بِكَ مِنَ الْجُبْنِ وَأَعُوذُ بِكَ مِنْ أَنْ أَرُدَّ إِلَى أَرْذَلِ الْعُمُرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الدُّنْيَا وَعَذَابِ الْقَبْرِ»  

"Sa'd used to teach his children these words as a teacher teaches his students, and he would say that the Messenger of Allah [SAW] used to seek refuge (with Allah) with these words at the end of every prayer: 'Allahumma inni a'udhu bika minal-bukhli, wa a'udhu bika mnal-jubni, wa a'udhu bika an uradda ila ardhalil-'umuri, wa a'udhu bika min fitnatid-dunya, wa min 'adhabil-qabr (O Allah, I seek refuge with You from miserliness, and I seek refuge with You from cowardice, and I seek refuge with You from reaching the age of senility, and I seek refuge with You from the trials of this life and the torment of the grave.)'" (Using translation from Nasāʾī 5479)  

عَنْ مُصْعَبِ بْنِ سَعْدٍ وَعَمْرِو بْنِ مَيْمُونٍ الْأَوْدِيِّ قَالَا كَانَ سَعْدٌ يُعَلِّمُ بَنِيهِ هَؤُلَاءِ الْكَلِمَاتِ كَمَا يُعَلِّمُ الْمَكْتَبُ الْغِلْمَانَ وَيَقُولُ إِنَّ رَسُولَ اللهِ ﷺ كَانَ يَتَعَوَّذُ بِهِنَّ فِي دُبُرِ كُلِّ صَلَاةٍ «اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْبُخْلِ وَأَعُوذُ بِكَ مِنَ الْجُبْنِ وَأَعُوذُ بِكَ مِنْ أَرْذَلِ الْعُمُرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الدُّنْيَا وَعَذَابِ الْقَبْرِ»  

The Prophet [SAW] used to seek refuge with Allah from cowardice, miserliness, the tribulation of the heart and the torment of the grave. (Using translation from Nasāʾī 5443)  

أَنَّ النَّبِيَّ ﷺ كَانَ يَتَعَوَّذُ مِنَ الْجُبْنِ وَالْبُخْلِ وَسُوءِ الْعُمُرِ وَفِتْنَةِ الصَّدْرِ وَعَذَابِ الْقَبْرِ  

"The Prophet [SAW] used to seek refuge (with Allah) from five things: From miserliness, cowardice, reaching the age of second childhood, the tribulation of the heart and the torment of the grave." (Using translation from Nasāʾī 5446)

"I heard 'Umar bin Al-Khattab say: 'The Messenger of Allah [SAW] used to seek refuge with Allah from five things and say: Allahumma inni a'udhu bika minal-jubni, wal-bukhli, wa suw'il-'umuri, wa fitnatis-sadri wa 'adhabil-qabr (O Allah, I seek refuge with You from cowardice, miserliness, reaching the age of second childhood, the trials of the heart and the torment of the grave.)'" (Using translation from Nasāʾī 5481)  

سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ يَقُولُ كَانَ رَسُولُ اللهِ ﷺ يَتَعَوَّذُ مِنْ خَمْسَةٍ اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْجُبْنِ وَالْبُخْلِ وَسُوءِ الْعُمُرِ وَفِتْنَةِ الصَّدْرِ وَعَذَابِ الْقَبْرِ
