Volume 3, Book 31, Number 162:
Narrated Ibn Abi Aufa:
We were in the company of Allah’s Apostle on a journey. He said to a man, “Get down and mix
Sawiq (powdered barley) with water for me.” The man said, “The sun (has not set yet), O Allah’s
Apostle.” The Prophet again said to him, “Get down and mix Sawiq with water for me.” The man
again said, “O Allah’s Apostle! The sun!” The Prophet said to him (for the third time) “Get down and
mix Sawiq with water for me.” The man dismounted and mixed Sawiq with water for him. The
Prophet drank it and then beckoned with his hand (towards the East) and said, “When you see the
night falling from this side, then a fasting person should break his fast.”
