1. My father, may Allah grant him mercy, said: We were told by Muhammed bin Abi’l-Qasem, from Muhammed bin Ali al-Kufi, from Uthman bin Isa, from Mu’awiya bin Wahab, that he said: We were at the place of Abu Abdillah, peace be upon him, and a man recited: «Say: I seek refuge in the Lord of the falaq» (113:1). Then the man said: What is the falaq? He said: A cut in the Fire in which there are seventy countries, in every country there are sevent thousand houses, in every house there are seventy thousand snakes, in the inside of every snake there are seventy thousand jars of poison which the people of the Fire must pass by.
