18. It is narrated from the narrator of the previous Hadith from his father from certain persons of our people who has said the following: “Once, pigeons were mentioned before abu ‘Abd Allah (a.s.), and a man said, ‘It has come to my knowledge that once ‘Umar saw a pigeon flying and a man underneath was running. ‘Umar then said, “One Satan runs under another Satan.” Abu ‘Abd Allah (a.s.), then said, ‘(It is because) Tsma‘il was not there with you.’ Someone then asked, ‘Was he (Tsma‘il) a friend (of pigeons)?’ He (the Imam) said, ‘The pigeons of al-Haram (the sacred area) are of the remaining pigeons of Tsma‘il.’”
