I am extremely fond of the latter part of the prayer.
One of the most effective ways of dealing with worries about the future is to recite this du’a which the Prophet (peace and blessings of Allah 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 Allah, 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 Allah, 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)
If a person utters these du’as, which ask that his spiritual and worldly affairs may be set right or corrected, with proper presence of mind and sincerity of intention, whilst striving to achieve that, Allah will grant him what he has prayed for, hoped for and striven for, and He will turn his worry into joy and happiness.
