Sahih Muslim · Book 48: The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness · The Virtue Of The Supplication: "O Allah, Give Us Good In This World And Good In The Hereafter, And Save Us From The Torment Of The Fire"
Anas reported that Allah's Messenger (ﷺ) used to supplicate (in these words):
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا شُعْبَةُ ، عَنْ ثَابِتٍ ، عَنْ أَنَسٍ ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقُولُ " رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ " .
" Our Lord, grant us the good in this world and the good in the Hereafter and save us from the torment of Hell Fire."
