Yazid bin Harun- Sufyan bin Husain- Al-Hakam bin ‘Utaybah- Ibrahim (b. Yazid al-Taymi)- Yazid al-Taymi- Abu Dharr said: I was sitting behind the Apostle of Allah who was riding a donkey while the sun was setting. He asked: Do you know where this sets? I replied: Allah and his Apostle know best. He said: It sets in a spring of warm water. (Sunan Abu Dawud, Hadith 3991)
