Sahih Muslim 2724
Sahih Muslim · Book 48: The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness · Supplications [Of The Prophet (SAW)]
This hadith has been transmitted on the authority of Abu Huraira that Allah's Messenge; (ﷺ) used to supplicate thus:
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، حَدَّثَنَا لَيْثٌ ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ ، عَنْ أَبِيهِ ، عَنْ أَبِي، هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَقُولُ " لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ أَعَزَّ جُنْدَهُ وَنَصَرَ عَبْدَهُ وَغَلَبَ الأَحْزَابَ وَحْدَهُ فَلاَ شَىْءَ بَعْدَهُ " .
" There is no god but Allah, the One Who conferred upon His armies the honour of victory and helped His servant rout the clans; there is nothing after that."
