Narrated 'Umarah bin 'Umair:"When the heads of 'Ubaidullah bin Ziyad and his companions were brought, they were stacked in the Masjid at Ar-Rahbah. So I came to them and they were saying: 'It has come, it has come." And behold, there was a snake going between the heads, until it entered the nostrils of 'Ubaidullah bin Ziyad, and it remained there momentarily, then left and went until it had disappeared. Then they said: 'It has come, it has come.' So it did that two or three times
