أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ أَيُّوبَ، قَالَ أَنْبَأَنَا وَكِيعٌ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَاصِمٍ، عَنْ زِرٍّ، قَالَ قُلْنَا لِحُذَيْفَةَ أَىَّ سَاعَةٍ تَسَحَّرْتَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ هُوَ النَّهَارُ إِلاَّ أَنَّ الشَّمْسَ لَمْ تَطْلُعْ ‏.‏

Zirr bin Hubaish said

"I had Sahur with Hudhaifah, then we went out to pray. When we came to the Masjid we prayed two Rakahs, then the Iqamah for prayer was said, and there was only a short time between them." Abu Hurairah said : "The Messenger of Allah said: 'Eat Sahur, for in Sahur there is blessing."
