Narrated Yusuf bin Mahik: I was in the house of `Aisha, the mother of the Believers. She said, "This revelation: "Nay, but the Hour is their appointed time (for their full recompense); and the Hour will be more previous and most bitter." (54.46) was revealed to Muhammad at Mecca while I was a playfull little girl."

Narrated Ibn `Abbas: While in his tent on the day the Battle of Badr, the Prophet 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 by the hand and said, "That is enough, O Allah's Messenger! You have appealed to your Lord too pressingly" The Prophet 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)
