A Frequent Du’a which The Messenger sallahu alayhi wa salam used to make:

اللَّهُمَّ أَصْلِحْ لِي دِينِي الَّذِي هُوَ عِصْمَةُ أَمْرِي، وَأَصْلِحْ لِي دُنْيَايَ الَّتِي فِيهَا مَعَاشِي، وَأَصْلِحْ لِي آخِرَتِي الَّتِي فِيهَا مَعَادِي، وَاجْعَلِ الْحَيَاةَ زِيَادَةً لِي فِي كُلِّ خَيْرٍ، وَاجْعَلِ الْمَوْتَ رَاحَةً لِي مِنْ كُلِّ شَرٍّ

Allahumm-aslih li dining alladhi huwa ‘ismatu amri, wa aslih li dunyaya-llati fiha ma’ashi, wa aslih li akhirati-llati fiha ma’adi, waj’alil-hayata ziyadatan li fi kulli khair, waj’alil-mauta rahatan li min kulli sharrin

The Translation :

O Allah, make my religion easy for me by virtue of which my affairs are protected, set right for me my world where my life exists, make good for me my Hereafter which is my resort to which I have to return, and make my life prone to perform all types of good, and make death a comfort for me from every evil.

Ash-Shaykh Bin Baaz, rahimahullah, said regarding the above du’a :

فإذا دعا به في سجوده أو دعا به في آخر التحيات، أو دعا به في خارج الصلاة كله طيب، ولو دعا ببعضه فلا حرج في ذلك

If the person were to supplicate with it in his sujood or supplicate with it at the end of his tashahud or to supplicate with it outside of the prayer,then all of that is considered okay and (even) if he were to supplicate with some of it (i.e. a portion from the du’a) then there is no sin in (doing) that
