Imam al-Ahnaf bin Qays (may Allah have mercy on him) narrates that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said to me: "O Ahnaf! Whoever laughs a great deal, his awe diminishes; whoever jokes is taken lightly; and whoever does something a great deal becomes known for it. Whoever talks a great deal, his slips become many; whoever's slips become many, his modesty diminishes; whoever's modesty diminishes, his piety diminishes; and whoever's piety diminishes, his heart dies."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Umar (may Allah be pleased with him) only with this chain, and Ibn Aishah (may Allah have mercy on him) is alone in narrating it."
