Sunan an-Nasa'i, Book 50, Hadith 54 (In-Book) ⓘ
It was narrated that 'Urwah bin Maimun said: "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.)'"
أَخْبَرَنَا سُلَيْمَانُ بْنُ سَلْمٍ الْبَلْخِيُّ، - هُوَ أَبُو دَاوُدَ الْمَصَاحِفِيُّ - قَالَ أَنْبَأَنَا النَّضْرُ، قَالَ أَنْبَأَنَا يُونُسُ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَمْرِو بْنِ مَيْمُونٍ، قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ، يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَتَعَوَّذُ مِنْ خَمْسٍ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْجُبْنِ وَالْبُخْلِ وَسُوءِ الْعُمُرِ وَفِتْنَةِ الصَّدْرِ وَعَذَابِ الْقَبْرِ " .
