Ibn Majah (1946) narrated it from Harmala bin Yahya, who said, "Abdullah bin Wahb told us, saying, Ibn Lahia informed me, from Abu Aswad, from Urwa, from Abdullah bin Zubayr," and he related it.Its chain of transmission is hasan because of Ibn Lahia, about whom there is well-known discussion, except that the narration of the Abadila from him is more reliable than that of others, and this is one of theirs.
