One who Does not Eat Meat for Forty Days his Manners Change

2. A number of our people have narrated from Ahmad ibn Muhammad from Ahmad ibn Muhammad from ibn abu Nasr from al-Husayn ibn Khalid who has said the following: “I once said to abu al-Hassan, al-Rida’ عليه السلام, ‘People say that if one does not eat meat for three days his manners change to worse.’ He (the Imam) said, ‘They have spoken lies. However, one who does not eat meat for forty days his manners change and it is because the seed (sperm) transfers (from one stage of development to another) within the duration of forty days.”
