Yahya related to me from Malik from Ibn Himas from his paternal
uncle from Abu Hurayra that the Messenger of Allah, may Allah bless
him and grant him peace, said, "Madina will be left in the best way
that it is until a dog or wolf enters it and urinates on one of the
pillars of the mosque or on the mimbar." They asked, "Messenger of
Allah! Who will have the fruit at that time?" He replied, "Animals
seeking food, birds and wild beasts."
