Hadith 1604
Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) narrates: There was a disagreement between two men regarding the mosque which was founded on piety. One of them said that it refers to the mosque of Madinah (i.e., Masjid Nabawi). The other said that it refers to Masjid Quba. They both came to the service of the Prophet (peace and blessings be upon him), so he said: "It refers to this mosque of mine."
