"The Messenger of Allah said, at the time of Sahur. 'O Anas, I want to fast, so give me something to eat.' So I brought him some dates and a vessel of water. That was after the Adhan of Bilal. He said: 'O Anas, find a man to come and eat with me.' So I called Zaid bin Thabit, who came and said: "I drank some Sawiq and I want to fast.' The Messenger of Allah said: "I also want to fast.' So he ate Sahr with him, then he got up and prayed two Rak'ahs, then he went out to the prayer." (Using translation from Nasāʾī 2167)  

قَالَ رَسُولُ اللهِ ﷺ وَذَلِكَ عِنْدَ السَّحَرِ «يَا أَنَسُ إِنِّي أُرِيدُ الصِّيَامَ أَطْعِمْنِي شَيْئًا» فَأَتَيْتُهُ بِتَمْرٍ وَإِنَاءٍ فِيهِ مَاءٌ وَذَلِكَ بَعْدَمَا أَذَّنَ بِلَالٌ قَالَ «يَا أَنَسُ انْظُرْ رَجُلًا يَأْكُلُ مَعِي» فَدَعَوْتُ زَيْدَ بْنَ ثَابِتٍ فَجَاءَ فَقَالَ إِنِّي شَرِبْتُ شَرْبَةَ سَوِيقٍ وَأَنَا أُرِيدُ الصِّيَامَ فَقَالَ رَسُولُ اللهِ ﷺ «وَأَنَا أُرِيدُ الصِّيَامَ» فَتَسَحَّرَ مَعَهُ ثُمَّ قَامَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ خَرَجَ إِلَى الصَّلَاةِ
