Sunan an-Nasa'i, Book 50, Hadith 51 (In-Book)

Mus'ab bin Sa'd said that : Sa'd used to teach him these words, narrating from the Prophet [SAW]: "Allahumma inni a'udhu bika minal-bukhli, wa a'udhu bika minal-jubni, wa a'udhu bika an uradda ila ardhalil-'umuri, wa a'udhu bika min fitnatid-dunya wa '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 in You from the trials of this world and the torment of the grave.)"

أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا أَبُو دَاوُدَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، قَالَ سَمِعْتُ مُصْعَبَ بْنَ سَعْدٍ، قَالَ كَانَ سَعْدٌ يُعَلِّمُهُ هَؤُلاَءِ الْكَلِمَاتِ وَيَرْوِيهِنَّ عَنِ النَّبِيِّ صلى الله عليه وسلم ‏ "‏ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْبُخْلِ وَأَعُوذُ بِكَ مِنَ الْجُبْنِ وَأَعُوذُ بِكَ مِنْ أَنْ أُرَدَّ إِلَى أَرْذَلِ الْعُمُرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الدُّنْيَا وَعَذَابِ الْقَبْرِ ‏" ‏ ‏.‏
