Sur (15), and it was narrated (16) by 'Umar ibn Shabbah (17) in his book "Qudat al-Basra" (Judges of Basra) through several channels (18); one of which is from al-Sha'bi, that Ka'b ibn Sur was sitting with 'Umar ibn al-Khattab when a woman came and said: O Commander of the Faithful, I have never seen a man better than my husband; by Allah, he spends his night in prayer and his day fasting.
