6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Hisham ibn Salim who has said the following: “About the case of the seeds which are from man and Satan when they share, abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘Perhaps it is created from one of them or perhaps from both of them together.’”
