It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Two qualities are never combined in a hypocrite: good conduct and bearing, and understanding of the religion."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Khalaf bin Ayyub narrated this hadith from Awf, and Abu Kurayb is alone in narrating it."
