It is reported about Imam Zayn al-Abidin that he saw a man who came to an open space near the blessed grave of the Prophet (peace and blessings be upon him), entered it and began making supplication. Imam Zayn al-Abidin (may Allah be pleased with him) forbade him and said: "Shall I not narrate to you a hadith which I heard from my father, from my grandfather, from the Prophet (peace and blessings be upon him)? He said: 'Do not make my grave a place of festivity, and do not make your houses graves, for wherever you are, your greeting of peace will reach me.'"
Imam Abu Ya'la recorded this. Its chain contains a narrator, Hafs bin Ibrahim al-Ja'fari, whom Ibn Abi Hatim mentioned without mentioning any criticism (jarh) of him; the rest of its narrators are thiqat (trustworthy).
