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."
