1591 - Abu Abd Allah narrated to us, saying: Yahya narrated to us, from Sufyan, saying: Abu Ishaq narrated to me, from Abu Layla al-Kindi, who said: Hujr ibn 'Adi saw a son of his being negligent with [the performance of] ablution (wudu'), so he said: "Bring the scroll. This is what we were told: that ablution is half of faith."
