Visiting the Prophet's Grave ﷺ by Shaykh Mis'ad al-Ḥusaynī (حفطه الله)

Allah’s Messenger (ﷺ) said, “Do not make your houses graves, and do not make my grave an ‘Eid’ (place of gathering). But invoke blessings on me, for your blessings reach me wherever you may be.”
Sunan Abu Dawood vol.1, no.1796
The Messenger of Allah (ﷺ) said, "“May Allah curse the Jews and the Christians, for they took the graves of their Prophets as places of worship.” ‘Aishah (may Allah be pleased with her) said, “He was warning against what they had done.”
