سنن أبي داود

Narrated Tawus:

Ibn 'Umar was asked about praying two rak'ahs before the Maghrib prayer. He replied: I did not see anyone praying them during the time of the Messenger of Allah (ﷺ). He (Ibn Umar) permitted to pray two rak'ahs after the Asr prayer.

Abu Dawud said: I heard Yahya b. Ma'in say: The correct name of the narrator Abu Shu'aib is the Shu'aib. Shu'bah made a mistake in narrating his name.
