Malik related to me from Abu'z-Zinad from al-Araj from Abu
Hurayra that the Messenger of Allah, may Allah bless him and grant him
peace, said, "The fire of the children of Adam which they kindle is a
seventieth part of the fire of Jahannam." They said, "Messenger of
Allah, this fire is certainly enough." He said, "That fire is sixty-
nine times greater."
Muwatta Malik Book 57, Hadith 1
