Sahih Bukhari Volume 6, Book 65, Hadith 4879

حَدَّثَنِي إِسْحَاقُ، حَدَّثَنَا خَالِدٌ، عَنْ خَالِدٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ وَهْوَ فِي قُبَّةٍ لَهُ يَوْمَ بَدْرٍ ‏"‏ أَنْشُدُكَ عَهْدَكَ وَوَعْدَكَ، اللَّهُمَّ إِنْ شِئْتَ لَمْ تُعْبَدْ بَعْدَ الْيَوْمِ أَبَدًا ‏"‏‏.‏ فَأَخَذَ أَبُو بَكْرٍ بِيَدِهِ وَقَالَ حَسْبُكَ يَا رَسُولَ اللَّهِ فَقَدْ أَلْحَحْتَ عَلَى رَبِّكَ‏.‏ وَهْوَ فِي الدِّرْعِ فَخَرَجَ وَهْوَ يَقُولُ ‏"‏ ‏{‏سَيُهْزَمُ الْجَمْعُ وَيُوَلُّونَ الدُّبُرَ * بَلِ السَّاعَةُ مَوْعِدُهُمْ وَالسَّاعَةُ أَدْهَى وَأَمَرُّ‏}‏‏"‏

Narrated By Ibn Abbas : While in his tent on the day the Battle of Badr, the Prophet said, "O Allah! I request You (to fulfil) Your promise and contract. O Allah! It You wish that the Believers be destroyed). You will never be worshipped henceforth." On that, Abu Bakr held the Prophet by the hand and said, "That is enough, O Allah's Apostle! You have appealed to your Lord too pressingly" The Prophet was wearing his armour and then went out reciting: 'Their multitude will be put to flight and they will show their backs. Nay, but the Hour is their appointed time (for their full recompense), and the Hour will be more previous and most bitter.' (54.45-46)
