Narrated Ibn 'Abbas:
The Messenger of Allah (ﷺ) led us in prayer at Medina eight of seven rak'ahs, in the noon and afternoon prayers, and the sunset and night prayers. The narrator Sulaiman and Musaddad did not say the words "led us".Abu Dawud said: The aforesaid tradition has also been narrated by Salih, the client of Tu'mah on the authority if Ibn 'Abbas saying: "Not during rain."
