Al-Kāfi 2, narration 9

Translation

2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ibn ‘Udhayna from Zurara who has said the following: “Once a man asked abu Ja’far (a.s.) about the words of Allah, the Majestic the Glorious, ‘When your Lord took from the back of the children of Adam their offspring and told them to bear testimony to the words of Allah, “Am I not your Lord,” they all said, “Yes, You are our Lord. . . .”’ (7:172) “He (the Imam), while his father (a.s.) was listening, said, ‘My father narrated to me that Allah, the Majestic, the Glorious, took a handful of clay, from which He created Adam. He poured upon it sweet water from Euphrates and left it for forty mornings. Then He poured upon it very salty water and left it for forty mornings. When the clay fermented He then kneaded it strongly and they (children of Adam) appeared as particles from his right and left sides. He ordered all of them to enter the fire. The people of the right hand entered it and it became cool and peaceful for them but the people of the left hand refused to enter.’”
