Narated By Tawus : Ibn ‘Umar was asked about praying two rak’ahs before sunset prayer. He replied: I did not see anyone praying during the times of the Apostle of Allah (PBUH). He permitted to pray two rak’ahs after the afternoon prayer.
Abu Dawud said: I heard yahya b. Ma’in say: The correct name of the narrator Abu Shu’aib is Shu’aib. Shuaib made a mistake in narrating his name.
