Sahih al-Bukhari · Book 20: Virtues of Prayer at Masjid Makkah and Madinah · To go to the Mosque of Quba
Narrated Ibn `Umar:
حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا يَحْيَى ، عَنْ عُبَيْدِ اللَّهِ ، قَالَ حَدَّثَنِي نَافِعٌ ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَأْتِي قُبَاءً رَاكِبًا وَمَاشِيًا. زَادَ ابْنُ نُمَيْرٍ حَدَّثَنَا عُبَيْدُ اللَّهِ عَنْ نَافِعٍ فَيُصَلِّي فِيهِ رَكْعَتَيْنِ .
The Prophet (ﷺ) 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)."
