A dua of The Messenger of Allah (ﷺ) was like this:

اَللَّهُمَّ إِنَّا نَسْأَلُكَ مُوْجِبَاتِ رَحْمَتِكَ وَعَزَائِمَ مَغْفِرَتِكَ وَالسَّلَامَةَ مِنْ كُلِّ إِثْمٍ وَالْغَنِيْمَةَ مِنْ كُلِّ بِرٍّ وَالْفَوْزَ بِالْجَنَّةِ وَالنَّجَاةَ بِعَوْنِكَ مِنَ النَّارِ

Allaahumma inna nas'aluka mu-jibaati ra’hmatika, wa 'azaa'ima maghfiratika, was-salaamata min kulli ithmin, wal-ghanimata min kulli birrin, wal-fawza bil- jannati, wan najaata bi ‘awnika minan-naar

O Allah! I beg You for that which incites Your Mercy and the means of Your forgiveness, safety from every sin, the benefit from every good deed, success in attaining Jannah and deliverance from Fire.
