Sahih Muslim Book 7, Hadith Number 3230.

Chapter : Eminence of the mosque of Quba; and excellence of prayer in it.

‘Abdullah b. ‘Umar reported that Allah’s Messenger (may peace be upon him) used to come to Quba’, i.e. (he came) on every Saturday, and he used to come riding or on foot. Ibn Dinar (another narrator) said that Ibn Umar used to do like this. This Hadith has been narrated on the authority of Ibn Dinar, but he made no mention of: “Every Saturday.”
