Sahih Bukhari 1941

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ ، عَنْ أَبِي إِسْحَاقَ الشَّيْبَانِيِّ ، سَمِعَ ابْنَ أَبِي أَوْفَى رَضِيَ اللَّهُ عَنْهُ ، قَالَ : كُنَّا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفَرٍ ، فَقَالَ لِرَجُلٍ : انْزِلْ فَاجْدَحْ لِي ، قَالَ : يَا رَسُولَ اللَّهِ ، الشَّمْسُ ، قَالَ : انْزِلْ فَاجْدَحْ لِي ، قَالَ ، يَا رَسُولَ اللَّهِ ، الشَّمْسُ ، قَالَ : انْزِلْ فَاجْدَحْ لِي ، فَنَزَلَ فَجَدَحَ لَهُ فَشَرِبَ ، ثُمَّ رَمَى بِيَدِهِ هَاهُنَا ، ثُمَّ قَالَ : إِذَا رَأَيْتُمُ اللَّيْلَ أَقْبَلَ مِنْ هَاهُنَا ، فَقَدْ أَفْطَرَ الصَّائِمُ ، تَابَعَهُ جَرِيرٌ ، وَأَبُو بَكْرِ بْنُ عَيَّاشٍ ، عَنْ الشَّيْبَانِيِّ ، عَنْ ابْنِ أَبِي أَوْفَى ، قَالَ : كُنْتُ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفَرٍ .

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.
