Ka'b swore to him: "By Allah (SWT) Who parted the sea for Musa, we find in the Tawrah that when Dawud, the Prophet of Allah, finished his prayer, he would say: 'Allahumma Aslih li dinya-lladhi ja'altahu li ismatan wa aslih li dunyaya-llati ja'alta fiha ma'ashi, Allahumma inni a-udhu biridaka min sakhatik wa a-udhu bi'afwika min naqmatika wa a-udhu bika mink, la mani' lima a'taita wa la mu'tia lima mana'ta wa la yanfa'u dhal-jaddi minka al-jadd (O Allah, set straight my religious commitment that You have made a protection for me, and set straight my worldly affairs which You have made a means of my livelihood. O Allah, I seek refuge in Your pleasure from Your wrath, and I seek refuge in Your forgiveness from Your punishment, and I seek refuge in You from You. None can withhold what you have given and none can give what you have withheld, and no wealth or fortune can avail the man of wealth and fortune before You.)'" He said: "And Ka'b told me that Suhaib told him that Muhammad ﷺ used to say (these words) when he had finished praying.'"  

أَنَّ كَعْبًا حَلَفَ لَهُ بِاللَّهِ الَّذِي فَلَقَ الْبَحْرَ لِمُوسَى إِنَّا لَنَجِدُ فِي التَّوْرَاةِ أَنَّ دَاوُدَ نَبِيَّ اللَّهِ ﷺ كَانَ إِذَا انْصَرَفَ مِنْ صَلاَتِهِ قَالَ اللَّهُمَّ أَصْلِحْ لِي دِينِي الَّذِي جَعَلْتَهُ لِي عِصْمَةً وَأَصْلِحْ لِي دُنْيَاىَ الَّتِي جَعَلْتَ فِيهَا مَعَاشِي اللَّهُمَّ إِنِّي أَعُوذُ بِرِضَاكَ مِنْ سَخَطِكَ وَأَعُوذُ بِعَفْوِكَ مِنْ نِقْمَتِكَ وَأَعُوذُ بِكَ مِنْكَ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ مُعْطِيَ لِمَا مَنَعْتَ وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ قَالَ وَحَدَّثَنِي كَعْبٌ أَنَّ صُهَيْبًا حَدَّثَهُ أَنَّ مُحَمَّدًا ﷺ كَانَ يَقُولُهُنَّ عِنْدَ انْصِرَافِهِ مِنْ صَلاَتِهِ  

Ka'b swore to him: "By Allah (SWT) Who parted the sea for Musa, we find in the Tawrah that when Dawud, the Prophet of Allah, finished his prayer, he would say: 'Allahumma Aslih li dinya-lladhi ja'altahu li ismatan wa aslih li dunyaya-llati ja'alta fiha ma'ashi, Allahumma inni a-udhu biridaka min sakhatik wa a-udhu bi'afwika min naqmatika wa a-udhu bika mink, la mani' lima a'taita wa la mu'tia lima mana'ta wa la yanfa'u dhal-jaddi minka al-jadd (O Allah, set straight my religious commitment that You have made a protection for me, and set straight my worldly affairs which You have made a means of my livelihood. O Allah, I seek refuge in Your pleasure from Your wrath, and I seek refuge in Your forgiveness from Your punishment, and I seek refuge in You from You. None can withhold what you have given and none can give what you have withheld, and no wealth or fortune can avail the man of wealth and fortune before You.)'" He said: "And Ka'b told me that Suhaib told him that Muhammad ﷺ used to say (these words) when he had finished praying.'" (Using translation from Nasāʾī 1346)   

أَنَّ كَعْبًا حَلَفَ لَهُ بِالَّذِي فَلَقَ الْبَحْرَ لِمُوسَى أَنَّا نَجِدُ فِي الْكِتَابِ أَنَّ دَاوُدَ النَّبِيَّ ﷺ كَانَ إِذَا انْصَرَفَ مِنَ الصَّلَاةِ قَالَ «اللَّهُمَّ أَصْلِحْ لِي دِينِي الَّذِي جَعَلْتَهُ لِي عِصْمَةَ أَمْرِي وَأَصْلِحْ لِي دُنْيَايَ الَّتِي جَعَلْتَ فِيهَا مَعَاشِي اللَّهُمَّ إِنِّي أَعُوذُ بِكَ بِرِضَاكَ مِنْ سَخَطِكَ وَبِعَفْوِكَ مِنْ نِقْمَتِكَ وَأَعُوذُ بِكَ مِنْكَ اللَّهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ» وَحَدَّثَنِي كَعْبٌ أَنَّ صُهَيْبًا حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقُولُهُنَّ عِنْدَ انْصِرَافِهِ مِنْ صَلَاتِهِ  

[Machine] That Dawud, the Prophet of Allah ﷺ , used to say when he finished his prayer: "O Allah, reform my religion, which You have made the safeguard of my affairs, and reform my worldly life, in which You have placed my sustenance. O Allah, I seek refuge in Your pleasure from Your wrath, and I seek refuge in Your forgiveness from Your punishment, and I seek refuge in You from You. Nothing can withhold what You have given, nor can anyone give what You have withheld, and the wealth of this world cannot benefit its owner from You." Ka'b al-Ahbar said, and Suhaib informed me, that the Messenger of Allah ﷺ used to recite this supplication after finishing his prayer.  

أَنَّ دَاوُدَ نَبِيَّ اللهِ ﷺ كَانَ إِذَا انْصَرَفَ مِنْ صَلَاتِهِ قَالَ «اللهُمَّ أَصْلِحْ لِي دِينِي الَّذِي جَعَلْتَهُ عِصْمَةَ أَمْرِي وَأَصْلِحْ لِي دُنْيَايَ الَّذِي جَعَلْتَ فِيهَا مَعَاشِي اللهُمَّ إِنِّي أَعُوذُ بِرِضَاكَ مِنْ سَخَطِكَ وَأَعُوذُ بِعَفْوِكَ مِنْ نِقْمَتِكَ وَأَعُوذُ بِكَ مِنْكَ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ جَدُّهُ» قَالَ كَعْبُ الْأَحْبَارِ وَأَخْبَرَنِي صُهَيْبٌ أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَنْصَرِفُ بِهَذَا الدُّعَاءِ مِنْ صَلَاتِهِ  

Ka'b swore to him: "By Allah (SWT) Who parted the sea for Musa, we find in the Tawrah that when Dawud, the Prophet of Allah, finished his prayer, he would say: 'Allahumma Aslih li dinya-lladhi ja'altahu li ismatan wa aslih li dunyaya-llati ja'alta fiha ma'ashi, Allahumma inni a-udhu biridaka min sakhatik wa a-udhu bi'afwika min naqmatika wa a-udhu bika mink, la mani' lima a'taita wa la mu'tia lima mana'ta wa la yanfa'u dhal-jaddi minka al-jadd (O Allah, set straight my religious commitment that You have made a protection for me, and set straight my worldly affairs which You have made a means of my livelihood.

He said: "And Ka'b told me that Suhaib told him that Muhammad ﷺ used to say (these words) when he had finished praying.'" (Using translation from Nasāʾī 1346)   

«اللهُمَّ أَصْلِحْ لِي دِينِي الَّذِي جَعَلْتَهُ لِي عِصْمَةً وَأَصْلِحْ لِي دُنْيَايَ الَّتِي جَعَلْتَ فِيهَا مَعَاشِي اللهُمَّ إِنِّي أَعُوذُ بِرِضَاكَ مِنْ سَخَطِكَ وَأَعُوذُ ثُمَّ ذَكَرَ كَلِمَةً مَعْنَاهَا بِعَفْوِكَ مِنْ نِقْمَتِكَ وَأَعُوذُ بِكَ مِنْكَ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ» قَالَ وَحَدَّثَنِي كَعْبٌ أَنَّ صُهَيْبًا حَدَّثَهُ أَنَّ مُحَمَّدًا ﷺ كَانَ يَقُولُهُنَّ عِنْدَ انْصِرَافِهِ مِنْ صَلَاتِهِ  

"عَنْ كعْب أَنَّ دَاوُدَ - عَلَيْهِ السَّلاَم - كَان إذا انْصَرَفَ منْ صَلاته قَالَ: اللَّهُمَّ اصْلِح لى دينى الَّذِى جَعَلتَهُ لِى عِصْمَةً، وَأَصْلِح لِى دنيَاىَ الَّتِى جَعَلتَ فِيها مَعاشِى، اللَّهُمَّ أَعُوذ بِرِضَاكَ مِنْ سَخَطِكَ، وَأَعُوذُ بِعَفْوِكَ مِنْ نقْمَتِكَ، وَأَعُوذُ بكَ مِنْكَ، اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ، ولاَ مُعْطِىَ لا مَنَعْتَ، وَلاَ يَنْفَعُ ذَا الجدِّ مِنْكَ الجَدُّ قَالَ كعْبٌ وَحَدَّثَنى صُهَيْب أَنَّ مُحَمَّدًا ﷺ كَانَ يَقُولُهُنَّ عِنْدَ انْصَرَافِهِ مِنْ صَلاَتِهِ".
