Prophet (peace and blessings of Allaah be upon him) used to recite:
“Allaahumma aslih li deeni alladhi huwa ‘ismatu amri, wa aslih li dunyaaya allati fiha ma’aashi, wa aslih li aakhirati allati ilayha ma’aadi, waj’al al-hayaata ziyaadatan li fi kulli khayr, wa’l-mawta raahatan li min kulli sharr
(O Allaah, correct my religious commitment which is the foundation of my life, and correct my worldly affairs in which is my livelihood, and grant me good in the Hereafter to which is my return. Make my life a means of accumulating good, and make death a respite for me from all evil).” (Narrated by Muslim, 2720).
And he said,
“Allaahumma rahmataka arju fa la takilni ila nafsi tarfata ‘aynin wa aslih li sha’ni kullahu, laa ilaaha illa anta
(O Allaah, for Your mercy I hope, so do not abandon me to myself even for a moment. And correct all my affairs. There is no god but You).” (Narrated by Abu Dawood with a saheeh isnaad, no. 5090; classed as hasan by al-Albaani in Saheeh al-Kalim al-Tayyib, p. 49).
