Sahih al-Bukhari, Book 64, Hadith 158 (In-Book) ⓘ
Narrated Abu Huraira: Allah's Messenger used to say, "None has the right to be worshipped except Allah Alone (Who) honored His Warriors and made His Slave victorious, and He (Alone) defeated the (infidel) clans; so there is nothing after Him.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا اللَّيْثُ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَقُولُ " لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ، أَعَزَّ جُنْدَهُ، وَنَصَرَ عَبْدَهُ وَغَلَبَ الأَحْزَابَ وَحْدَهُ، فَلاَ شَىْءَ بَعْدَهُ " .
