20. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad, from Muhammad ibn Sinan from ibn Muskan from Yazid ibn Khalifah who has said the following: “In one side of my house there were two eggs of pigeon of al-Haram (the sacred area). The boy went to move the cluster not knowing that the eggs were there and he broke them. I went out and met ‘Abd Allah ibn al-Hassan and mentioned it to him. He said, ‘You must give charity of two handful of flour.’ I then met abu ‘Abd Allah عليه السلام, and informed him (the Imam) about it. He (the Imam) said, ‘Pay the price of two birds as feed for the pigeon of al-Haram (the sacred area).’ I then met ‘Abd Allah ibn al-Hassan and informed him about it and he said, ‘He (the Imam) has told you the truth. You can narrate it because he (the Imam) has taken it from his ancestors.’”
