Sahih al-Bukhari 4877
Narrated Ibn `Abbas:
While in his tent on the day the Battle of Badr, the Prophet (ﷺ) said, "O Allah! I request You (to fulfill) 
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 (ﷺ) by the hand and said, "That is enough, O 
Allah's Messenger (ﷺ)! You have appealed to your Lord too pressingly" The Prophet (ﷺ) was wearing his armor 
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)
