Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) reports that the Prophet (peace and blessings be upon him) said: "Whoever visits my grave, my intercession becomes binding for him."
Imam al-Bazzar recorded this. Its chain contains a narrator, Abdullah bin Ibrahim al-Ghifari, who is da'if (weak).
