سنن أبي داود

Nafi' said: Ibn 'Umar saw a man praying two rak'ahs after the Friday prayer on the same place (where he offered the Friday prayer). He pushed him and said: Do you offer four rak'ahs of Friday prayer ? 'Abd Allah (b. 'Umar) used to pray two rak'ahs in his house after the Friday prayer, and he used to say: This is how the Messenger of Allah (ﷺ) did.
