وَعَن سعد أَن كَانَ يُعَلِّمُ بَنِيهِ هَؤُلَاءِ الْكَلِمَاتِ وَيَقُولُ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَتَعَوَّذُ بِهِنَّ دُبُرَ الصَّلَاةِ: «اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْجُبْن وَأَعُوذُ بِكَ مِنَ الْبُخْلِ وَأَعُوذُ بِكَ مِنْ أَرْذَلِ الْعُمُرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الدُّنْيَا وَعَذَاب الْقَبْر» . رَوَاهُ البُخَارِيّ
English Translation
Sa'd said he used to teach his sons the following words, saying that God’s Messenger was accustomed to use them when committing himself to God’s protection at the end of prayer, “O God, I seek refuge in Thee from cowardice, I seek refuge in Thee from niggardliness, I seek refuge in Thee from the vilest kind of life, I seek refuge in Thee from the seduction of the world and the punishment in the grave.” Bukhari transmitted it.
