Narrated Ibn `Umar: The Prophet used to go to the Quba' mosque, sometimes walking, sometimes riding.

Narrated Nafi`: Ibn `Umar never offered the Duha prayer except on two occasions: (1) Whenever he reached Mecca; and he always used to reach Mecca in the forenoon. He would perform Tawaf round the Ka`ba and then offer two rak`at at the rear of Maqam Ibrahim. (2) Whenever he visited Quba, for he used to visit it every Saturday. When he entered the Mosque, he disliked to leave it without offering a prayer. Ibn `Umar narrated that Allah's Apostle used to visit the Mosque of Quba (sometime) walking and (sometime) riding.

And he (i.e. Ibn `Umar) used to say, "I do only what my companions used to do and I don't forbid anybody to pray at any time during the day or night except that one should not intend to pray at sunrise or sunset."

Narrated `Abdullah bin Dinar: Ibn `Umar said, "The Prophet used to go to the Mosque of Quba every Saturday (sometimes) walking and (sometimes) riding." `Abdullah (Ibn `Umar) used to do the same.

Narrated Ibn `Umar: The Prophet used to go to the Mosque of Quba (sometimes) walking and sometimes riding. Added Nafi` (in another narration), "He then would offer two rak`at (in the Mosque of Quba)."
