Mujahid (may Allah have mercy on him) narrates: We were sitting in a circle in which Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and Ubayd bin Umayr (may Allah have mercy on him) were present. A man came to us, stood over us and said: "Accept the invitation of so-and-so, accept the invitation of so-and-so." The people disliked it intensely, and Sayyiduna Ibn Umar (may Allah be pleased with them both) lowered his head. Then Ubayd bin Umayr (may Allah have mercy on him) raised his head and said: "O son of our brother, excuse us, excuse us." Then Sayyiduna Ibn Umar (may Allah be pleased with them both) raised his head and said: "Get up and come with us; there is no excusing oneself in this matter. I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Whoever is invited and does not accept has disobeyed Allah and His Messenger.'"
Imam al-Tabarani (may Allah have mercy on him) said: "Only Ibn al-Mubarak (may Allah have mercy on him) narrated this hadith from Ibn Awn, and al-Husayn bin al-Hasan al-Marwazi (may Allah have mercy on him) is alone in narrating it."
