Ishaq bin Abdullah al-Tufawi said: Whenever Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) mentioned the Prophet (peace and blessings be upon him), he would weep.
Imam al-Tabarani recorded this report in al-Mu'jam al-Awsat; I do not know Ishaq al-Tufawi, and the rest of its narrators have been declared trustworthy.
